Sky News reports that Paul was "super nice" to fans and football supporters, after Paul Novelli, who travelled from the US to Wrexham for the game, took a selfie with the actor.
Novelli, told the outlet that he simply rocked up to the Hollywood star, said "hi" and asked to take a photo with him.
When the supporter asked the actor if he was enjoying himself and having a good time, he is said to have replied with: "Amazing."
Fan, Novelli, who runs podcast called Up The Town, which is dedicated to Wrexham FC, even gave an insight into the chants the actor joined in with.
The outlet reports that some of the chants included Super Paul Mullin and Allez Allez Allez.
Novelli wasn't the only fan that Paul posed for a selfie with. In fact, he posed with countless locals and football fans while soaking up the atmosphere in the Welsh pub.

While another added: "Thanks for the pic Paul Rudd."
Meanwhile, other social media users reacted to the Hollywood star mingling with the locals.
"Loving the pictures of Paul Rudd having a pint with the Wrexham fans. Just because you are a so called superstar it doesn’t make you too good to share the craic with the 'little people'. Many could learn from this," penned one person on Twitter.
