During one of the run throughs, when Jim did his Klingon bit, I turned to Kevin and asked him, "Did he just say 'revenge is a dish best served cold' in Klingon?" like I was trying to figure out if that's actually what happened, like maybe I misunderstood him. Chuck Lorre told me that it would be funnier if I was more exasperated. "You're just here to play this game, and now some guy is quoting Klingon at you. This happens everywhere you go," he said.
I sighed dramatically, and said, "Oh, it does." Everyone laughed, hard, and Chuck pointed his finger at me. "Yes. That is exactly the way to play that beat."
When Chuck gave me that note, I grokked how to play Evil Wil Wheaton (The Big Bang Theory version), and I could see the comedy in every beat I played for the rest of the show. I totally grew a level in comedy acting, and learned something about letting go of who I really am, so I could embrace the Delightfully Evil version of myself (who I seriously hope will return in the future, because OMG was it fun to play him.)
You know, it occurs to me that some of you may have questions about what it was like to work on Big Bang Theory. If you leave them in the comments, I'll do my best to answer as many of them as I can today.
