Pattinson spoke to Ali Plumb of BBC Radio 1 about The Batman, where he was asked if he ever took any Bat-paraphernalia home with him from the set.
After admitting it's nearly impossible to sneak anything from these movie sets, Pattinson did talk about WB speaking with him about his sock-stealing.
The actor was so dedicated to playing the Caped Crusader that he found himself taking some of the socks home with him after filming scenes.
"I kept getting a talking to from Warner Bros.," Pattinson revealed. "They'd say, 'You know, it's fine to have a few, but you take them every day [laughs]. How many socks do you need, cause we've been shooting for a year?'"
Pattinson plays a young Bruce Wayne who is early in his career as Batman, with director Matt Reeves saying the film is inspired by the DC series' Batman: The Long Halloween by Jeph Loeb and Tim Sale, Darwyn Cooke's Batman: Ego and Other Tails, and Frank Miller and David Mazzucchelli's Batman: Year One.
The Batman arrives in theaters on March 4th.
