Last October, it was announced that Liam Neeson would replace Mel Gibson in 'The Hangover 2.' How'd he get the gig? The award-winning actor exchanged a few texts with 'Hangover' star (and his 'A-Team' co-star) Bradley Cooper.

Cooper sent him a simple "Do you want to be in Hangover 2?" text message while Neeson was drinking a glass of wine. "I was like, [he motions taking a sip and then texting] 'Yeah,'" he told Jay Leno on 'The Tonight Show.'

Cooper texted back, "Tomorrow?" Neeson took another sip and replied simply, "Yeah." Watch the video inside.
