Timeless will wrap up its series with a two-part TV movie in just two weeks!

Executive producers Eric Kripke, Shawn Ryan, and Arika Lisanne Mittman have promised to not let fans down with a finale that will journey through the past, present, and future. Lucy (Abigail Spencer), Wyatt (Matt Lanter), and the rest of the Time Team will stop at nothing to save Rufus (Malcolm Barrett) and also battle Rittenhouse along the way.
