Jimmy Fallon

An ingratiating comedian and actor with a knack for impersonations and musical parodies, Jimmy Fallon brought boyish energy to the venerable sketch comedy series "Saturday Night Live" (NBC, 1975- ) between 1998 and 2004. His tenure on the show, which included a sublime pairing with head writer Tina Fey as co-anchors of "Weekend Update," led to several high-profile television stints and film roles.

Fallon thrived in live-audience settings like serving as the host of the "MTV Movie Awards" in 2002, while perhaps not living up to full potential on the big screen with forgettable appearances in otherwise noteworthy films like "Almost Famous" (2000) and "Band of Brothers" (HBO, 2001).

After a supporting role in the Woody Allen comedy "Anything Else" (2003), Fallon had his first starring role in the critically panned remake of Luc Besson's "Taxi" (2004). He fared better as a Red Sox-obsessed teacher in the romantic comedy "Fever Pitch." (2005). Despite fairly consistent work on the big screen, his movie career never quite panned out and Fallon kept a relatively low profile until 2008, when he was announced as Conan O'Brien's replacement to host "Late Night with Jimmy Fallon" (NBC, 2009-13).

Born James Thomas Fallon, Jr. in Brooklyn, NY, on Sept. 19, 1974, he was a die-hard "Saturday Night Live" fan from an early age, spending many hours recreating sketches from the show with his sister Gloria as they grew up in Saugerties. A regular performer in high school drama club productions and talent shows, Fallon made his stand-up debut at 17 and left college a semester shy of graduation in 1996 to pursue comedy in Los Angeles. By 1998, he was studying with the legendary improv group the Groundlings and earning his dues as a stand-up comic in local clubs.

Trimmed from his first two appearances in feature films, he made his official acting debut in a 1998 episode of "Spin City" (ABC, 1996-2002) just two months before he was summoned to New York to audition for "Saturday Night Live." His audition, filled with impersonations of Jerry Seinfeld, John Travolta, and former "SNL" breakout star Adam Sandler, won over producer Lorne Michaels, who hired him as a featured performer for the 1998-99 season. That same year, he penned a book of humor titled I Hate This Place: The Pessimist's Guide to Life with his sister Gloria.

Fallon's boundless energy, which frequently caused him to break character in the middle of sketches, and knack for characters in the grip of arrested development endeared him to audiences, and he was made a full cast member in the summer of 1999. Among his more memorable roles were Sully, one half of the hormonally charged "Boston Teens" with Rachel Dratch; chemically inspired college student and Internet talk show host Jarret; an ever-grumpy Barry Gibb opposite Justin Timberlake's Robin Gibb; and unpleasant tech support know-it-all Nick Burns. Fallon also gave note-perfect imitations of celebrities, both notable (Fallon played a younger Mick Jagger opposite the real article in a memorable episode) and otherwise (Carson Daly, Pat O'Brien). But his best showcase came as co-host of "Weekend Update" with Tina Fey, beginning in 2004, where he was frequently given airtime to perform song parodies or deliberately inane song tributes to upcoming holidays. Their chemistry as a team proved exceptionally popular with viewers, and helped elevate Fallon's standing as a possible breakout performer.

Fallon's first major appearance away from "SNL" was as co-host of the MTV Movie Awards in 2001, which was highlighted by his turn as Keanu Reeves' Neo in an amusing parody of both "The Matrix" (1999) and "Sex and the City" (HBO, 1998-2004). He followed this with a virtually unrecognizable performance as the ironically named Dennis Hope, manager for the ill-fated '70s rock band Sweetwater, in Cameron Crowe's instant classic, "Almost Famous." Fallon showed some dramatic potential in the film, most notably in its infamous plane-in-a-storm sequence, where Dennis admits to a particularly horrible deed. Fallon also played it straight for a cameo in Steven Spielberg and Tom Hanks World War II miniseries, "Band of Brothers" (HBO, 2001). Fallon returned to MTV to host the 2002 Video Music Awards, where his talent for impersonating rockers was highlighted in a show-stopping medley featuring his imitations of Avril Lavigne, The White Stripes, Eminem and others. Fallon himself cut an album that same year; an amusing blend of parody songs and stand-up bits, The Bathroom Wall earned a Grammy nomination for Best Comedy Album and even a hit single with "Idiot Boyfriend," a dead-on spoof of 1970s soul co-written by Blondie's Debbie Harry and Chris Stein.

Fallon's movie career appeared to kick into high gear in 2003 with major roles in two features, including the Woody Allen comedy "Anything Else." Unfortunately, both that film and his other feature that year, "The Entrepreneurs," were met with dismissal and even outright hostility by audiences and critics. Regardless, Fallon departed from "Saturday Night Live" in 2004 and began work on his next feature, the comedy "Taxi" with Queen Latifah. A remake of a 1998 French comedy by Gerard Pires, the film's loud, crass humor earned it a quick demise at the box office. Fallon returned to MTV for a third time to host the MTV Movie Awards in 2005 before beginning work on the romantic comedy "Fever Pitch" (2005), which was based on the novel by Nick Hornby. The film, which co-starred and was co-produced by Drew Barrymore, moved the action of the novel from England's football fields to Boston's Fenway Park, where diehard Red Sox fan Fallon meets and falls in love with Barrymore against the backdrop of the 2004 World Series race. The finale of the film featured Fallon and Barrymore racing out onto the field at Fenway to celebrate the Red Sox's first World Series win in 86 years. The film itself, however, was only a modest success at the box office.

Following the mediocre response to his movie efforts, Fallon kept a low profile for the next few years. He lent his voice to two animated efforts, "Doogal" (2006) and "Arthur and the Invisibles" (2007), and played Edie Sedgwick's promoter Chuck Wein in "Factory Girl" (2006), all of which were met with underwhelming box office numbers. He also kept busy on the comedy club circuit and contributed to the 2006 edition of The Secret Policeman's Ball, which raised money for Amnesty International. Fallon gained some positive press in 2007 for contributing the proceeds from his humorous song "Car Wash for Peace" to charity, and for giving a note-perfect parody of Internet sensation Lonleygirl15 in a video that made the rounds on the Web. Fallon's name returned to the news in 2008 when he was mentioned as a possible replacement for Conan O'Brien after the "Late Night" host assumed the mantle of "The Tonight Show" (NBC, 1954- ) in 2009. He was officially confirmed as O'Brien's successor in April of 2008, which was followed by a formal announcement in May, much to the surprise of many who had perhaps dismissed Fallon in the past, or who were surprised to see him front and center after a few years spent lying low. Though initially derided for his nervous debut, Fallon grew into his hosting duties over time and eventually drew increasingly higher ratings.

After successfully hosting the 2010 Emmys, in which he rocked the house with his opening musical send-up of Bruce Springsteen's "Born to Run," his own talk show earned its first Emmy Award nomination for Outstanding Variety, Music or Comedy Series in 2011. That same year, Fallon ran into a bit of trouble when he had Congresswoman Michelle Bachman on the show, where she took the stage while the band played a lyric-less version of the Fishbone funk tune "Lyin' Ass Bitch." After hearing a complaint from a prominent Democratic congresswoman, Fallon tweeted his apologies and joked that band leader Questlove was grounded. Meanwhile, after releasing his second comedy album Blow Your Pants Off (2012), he served as creator and executive producer of the sitcom "Guys with Kids" (NBC, 2012-13), which starred Anthony Anderson, Zack Cregger and Jesse Bradford as three regular guys trying to raise their young kids while their moms (Tempestt Bledsoe, Erinn Hayes and Jamie-Lynn Sigler) go off to work.

In March 2013, Fallon was the source of rampant rumors that he was about to take over "The Tonight Show" from Jay Leno. The rumors started when Leon began making scathing jokes about NBC on his show, calling the network "extinct" and executives "snakes" in his monologues. In an interview with GQ magazine, Fallon's "Late Night" producer Lorne Michaels all but confirmed the rumors, stating that "there's an inevitability" to the rumors that he might be moving up to 11:30, though further speculation entailed the host's desire to stay in New York rather than move to Los Angeles. After weeks of speculation, NBC made it official in April by announcing Fallon would be taking over as host of "The Tonight Show" in February 2014.
