Tom Cruise [1] and Mission: Impossible 5 director Chris McQuarrie accepted the ALS ice bucket challenge on Tuesday after being nominated by Hugh Jackman and the cast of Pan [2]. The guys took on a pretty heroic task — because the filming of the fifth installment of the action series hasn't officially started and the cast and crew of the movie are not all together yet, they were doused in ice cold water once for every person that was challenged. Basically, they accepted the challenge about eight times. You have to see it to believe it, so watch Tom's incredible effort in the video above, then check out more of the best celebrity ALS ice bucket challenges [3] we've seen so far.
