Who did Patton Oswalt play in Suits LA?

Patton Oswalt joined the cast of Suits LA as a guest star in episode 3, titled He Knew, and he played a fictional version of himself. In the episode, he's one of Ted Black's entertainment clients who was in on the ruse started by the firm's head of entertainment, Erica Rollins, and her associate, Leah.

In the scene in one of the offices of Black & Associates, Oswalt and Brian Baumgartner, another guest star in the episode playing a fictional version of himself, were talking about transitioning from comedian to drama actor. Oswalt is believed to have transitioned from being a comedian to a talk show host, so Baumgartner was asking for some advice.

However, it turns out into a verbal sparring between the two, with Patton Oswalt laughing at Brian Baumgartner for thinking that he could ever be an Oscar-worthy actor. As the argument breaks out, Oswalt yells at Baumgartner, who is known for his show The Office, saying:

"[The Office] is the dumbest show ever!"

However, it was all a ruse to put down Baumgartner. Per Erica, at the end of Suits LA episode 3, he needed a person to tell him that he couldn't do it so he could prove them wrong, and Patton Oswalt just so happened to be game to be the bad guy in that scene.

According to Oswalt, however, it was all acting. He clarified with NBC Insider in a feature published on March 10, 2025, saying:

"[The Office is] obviously not [dumb], I love that show. But it's fun to get to play that mean, you know?"
