Colin Farrell - Colin Farrell Spent A Night Alone On Total Recall Set

The Irish actor got into the mindset of factory worker/spy Douglas Quaid, the role made famous by Arnold Schwarzenegger in the 1990 original, by spending a night in the character's bed.

Farrell slept on the set with just his iPod music player, some books, candles, incense and a pot of green tea, and joked about the stunt by telling The Hollywood Reporter, "I just couldn't find the key for my hotel room."

He adds, "You do anything really, at times - that's not even doing much. But just any little bits and pieces just to create little bubbles of experience."
