Timeless is an American science fiction drama series that premiered on NBC on October 3, 2016. It follows the adventures of an unusual trio"?a history professor (Abigail Spencer), a scientist (Malcolm Barrett) and a soldier (Matt Lanter)"?as they attempt to stop Garcia Flynn (Goran Vinji?), a time-traveling criminal, from changing the course of American history. The series, largely based on the popular Spanish TV Series El ministerio del tiempo, was created by Shawn Ryan and Eric Kripke and also stars Paterson Joseph and Sakina Jaffrey. Executive producers include John Davis and John Fox of The Blacklist. Long considered one of NBC's hot pilots, it was ordered to series on May 13, 2016, after lengthy negotiations to obtain the series' "in-season stacking rights", which allow a network to stream all episodes of a series' current season via all the network's online platforms. The original episode order of season one has been increased from 13 to 16 on November 1, 2016.
