Yes, I photobombed U2! But that was all Ellen DeGeneres’s fault because she plied everyone with vodka on the red carpet. Her team was handing out these miniatures. A friend really wanted me to get a photo with U2. So I just saw the opportunity and I’ve never felt an impulse like it. I spotted them all standing around and I thought: Perfect! It wasn’t preordained or anything. I just did it.
[Re: ALS ice bucket challenge] Yes, well, Tom Hiddleston had done it once, and then the Internet was asking when I was going to do it and if I’d wear a white T-shirt apparently. And I actually did wear a white T-shirt for the last one, which they [the fans] were apparently quite happy about, so I was saving the Internet!
