When he left Doctor Who, Arthur Darvill was just the student.
OK, he had lived through a couple thousand years of fighting, but he was still just the Timelord's companion.
That's why it's so exciting that this go-round he gets to be the Time Master himself!
He will play a character named Rip Hunter who uses time travel to right wrongs throughout history.
Sound like anyone you Doctor Who fans know? LOLz!
The show is expected to debut next season on The CW as a midseason addition.
