My mom found a rerun of The Big Bang Theory where Paul Bettany was a guest star and he played a friend of one of the girls and so I'm wondering if Paul Bettany was a guest star on The Big Bang Theory before or did he star in other sitcoms before Wandavision?

Hi, Bestie! I am not sure, but I think he was on an episode where he was dating Amy. This was before he was Vision.
