The former 'O.C.' star worked alongside Brad on 2005 action movie 'Mr & Mrs Smith' - where he met Angelina Jolie and subsequently left wife Jennifer - and he believes he may have played a hand in The Changes in the actor's personal life.
He joked: ''In terms of [Brad and Angelina], I hooked them up. I was like, 'Brad, you don't want to do this, man, this Jen thing - I don't see it.' He heeded my advice and I'm happy for him.''
Discussing his own career, Adam - who is currently starring in 'Damsels in Distress', and has previously had parts in 'Jennifer's Body' and 'The Ring' - admits he picks movie roles according to his own personal tastes.
He told the Huffington Post: ''It's funny. I have been practical, but when I do look at my resume it does reflect my taste. Some I like more than others, but it does, by and large, reflect my taste, more than I think it would. [Especially] given how many things I've been willing to do that I don't personally care for.''
