The Deadpool actor is part-owner of the North Wales squad and was spotted at York Road on Tuesday night for his away game against Maidenhead in the National League.
Reynolds and fellow actor and co-owner Rob McElhenney made headlines after acquiring 100% of the Red Dragons in February of this year.
They took over from the Wrexham Supporters’ Trust and made a Â£ 2million investment under the terms of the deal.
Tuesday’s game was Wrexham’s first game the duo have attended since taking over the club.
Wrexham fan Andy Gilpin said he was “stunned” to see the Hollywood owners on York Road and that their appearance had “given fans a boost”.
âWe had an idea that they could have shown up today, but we didn’t really think that could happen until we saw them in the booth,â Mr Gilpin told the PA news agency.
âObviously that gave everyone a big boost – they’re there, you can see them, they were waving to the fans.
“We knew they were in the area and we knew they landed about six hours ago, but we thought it would probably be a game too far for them and then we saw a lot of flight attendants rushing in just before the kickoff, then the rumor spread that ‘yes they are there’.
âThere’s a hype and then there’s an appearance in Maidenhead that’s not really the kind of entry to Hollywood, it’s very low-key pitch, and seeing two Hollywood stars over there at the middle of the podium, we were just stunned you know.
âIt’s quite a statement to come here to Maidenhead and their fair play for doing it.
âThat they come here, it shows that they are serious.
âI didn’t expect them to be here, I thought they would save it for Torquay where they would have a red carpet entry and seeing them here was just amazing.
“I went downstairs and took a very blurry picture of two people waving to someone and to be honest it gave us all a good boost, it was really great to see them.”
After taking over in February, a statement from Reynolds and McElhenney read: âIt is a special day for both of us to become the final stewards in Wrexham AFC’s long and rich history.
“Together with the players, staff, fans and the local community, we can now pursue our goal of growing the squad and bringing them back to the EFL in the face of increased attendance and an improved stadium, while making a difference. positive for the wider Wrexham community.
âWrexham AFC is only able to prosper because of the incredible efforts of the Wrexham Supporters Trust.
“Their members perfectly reflect the integrity and spirit of the city and they will always have an important role in the club.”
