The "Free Guy" star, 44, took to Instagram on Tuesday to weigh in after Butler revealed in an interview from earlier this month that he doesn't watch Reynolds' films.
The Scottish actor, 51, also shared he didn't know about "Free Guy," which came out Aug. 13 and stars Reynolds as a man living inside a videogame.
"Can you believe Gerard Butler doesn’t know what Free Guy is?" the actor jokingly wrote, captioning a screenshot of two tweets. The first tweet links to a People article about Butler's comments, and the second is a tweet from Reynolds about supporting the American Civil Liberties Union and the National Association for the Advancement of Colored People. The latter tweet is circled.
"Also, can you believe that the challenges to democracy have never been greater and that Blake and I will match your contributions to the @aclu_nationwide and @naacp_ldf?" he added. "*Order of these questions optimized for the Internet, NOT importance."
On Twitter, Reynolds confirmed he will match all donations up to $1 million, split between the NCAAP's Legal Defense and Educational Fund and the ACLU through Oct. 8. "We still believe in you, 2021," the actor wrote. "Let’s help @ACLU and @naacp_ldf change it together."
In a Sept. 8 interview with UNILAD about his upcoming film "Copshop," Butler remarked that he wasn't aware of Reynolds' latest film.
"I actually don't know what Free Guy is," he said. When his "Copshop" co-star Alexis Louder informed him that it's Reynolds' latest movie, Butler responded: "Oh (expletive) is it?… I don’t watch Ryan Reynolds movies."
USA TODAY has reached out to Butler's reps for further comment.
Butler starred in the 2009 film "Gamer," about death row inmates forced to battle as part of a mind-control videogame. The same day "Free Guy" came out, "Slash Film" writer Chris Evangelista tweeted a poster of "Gamer," calling it, "The original FREE GUY"
"It could have been executed slightly differently, but I really loved the commentary it was making on where the world was going, especially in gaming and sort of losing ourselves into that world, and technology and man bonding with machine," Butler told UNILAD of "Gamer."
"But, I didn’t feel people really did get it at the time. It didn’t do amazing business. It has become a bit of a cult classic, but I didn’t know about this resurgence."
