Safety Not Guaranteed star Aubrey Plaza has confessed she really does believe in time travel.

The actress and comedian stars with Mark Duplass in the quirky comedy about a man who advertises for a partner to go back in time with him, and the reporter who replies so she can write a story about him.

Aubrey revealed: "I believe in spells, witchcraft, ghosts. I also believe in time travel although I haven't seen it with my own eyes, but am sure that it happens. If I could time travel I would go to London in 1969 and find Judy Garland and hang out with her!"

Safety Not Guaranteed was inspired by a genuine ad which appeared in survivalist magazine Backwoods Home in the mid-90s.

Writer Derek Connolly and director Colin Trevorrow penned the script, and created the character of magazine intern Darius especially for Aubrey after seeing her comedy show.

The 28-year-old actress said: "I was sent the script and told it was written specifically for me. I didn't know the writer or director but I really liked the story so said OK. The transformation that my character goes through is what really spoke to me."

Safety Not Guaranteed is in cinemas now.
