Pure Genius' Dermot Mulroney Was Totally Mistaken For Someone Who Wasn't Dylan McDermott

We can't believe it either

Kaitlin Thomas

It's a tale as old as time: Your friend casually mistakes Dermot Mulroney for Dylan McDermott (or vice versa) and then you have to kindly explain that just because two people have similar names made up of similar letters and the same amount of syllables they're actually two different people. It happens all the time! So often, in fact, that Saturday Night Live once created an entire sketch about it.

Knowing this, it was a little surprising when TVGuide.com asked Mulroney, who stars in CBS' upcoming medical drama Pure Genius, which famous celebrity he's been mistaken for and he gave a completely different answer, one that involves a certain Marvel superhero.

Watch the video above to find out which Avenger might want to watch his back on the off chance Mulroney decides to make a jump to the big screen.

Pure Genius premieres Thursday, Oct. 27 at 10/9c on CBS.
