Rob McElhenney and Ryan Reynolds have had great ventures together. We’ve seen them unfold on the popular series Welcome to Wrexham. And now, It’s Always Sunny in Philadelphia‘s Rob McElhenney will join Reynolds in Deadpool & Wolverine. In the latest episode of Welcome to Wrexham, which we saw via The News, Reynolds revealed, “Because of my busy schedule, I had to invite my cochair, Rob McElhenney, to the set of Deadpool in London to discuss all things that are Wrexham… And, yes, I did have to promise him a role in the upcoming Deadpool film. Now, I can’t necessarily tell you which character Rob plays in Deadpool for fear of being shot down by the Marvel drone that follows me and my kids around.” Deadpool & Wolverine is slated to have many cameos, and we can now count McElhenney in their number.

In the episode, Rob McElhenney couldn’t reveal his outfit because it would be a tease of his Deadpool & Wolverine role. “It’s super comfortable making superhero movies,” McElhenney noted. To which Reynolds snarked, “Thanks for doing a cameo. … For the record, Rob has never asked me to be on It’s Always Sunny in Philadelphia or Mythic Quest or his podcast or any of his other multimedia ventures.”

But what role will McElhenney actually play in Deadpool & Wolverine? That remains a mystery. Although, we might be inclined to say a TVA agent.
