Ryan Reynolds is auctioning off tickets to the premiere of his film X-Men Origins: Wolverine – with proceeds benefiting the Michael J. Fox Foundation for Parkinson’s Research. Ryan plays Deadpool in the movie, appearing alongside star Hugh Jackman, who reprises his X-Men role as Wolverine.

One lucky bidder will have the opportunity to attend the premiere and sit near Ryan.

“I am proud to be a part of this team of dedicated and motivated people who are getting out there and making a difference,” Ryan said in a statement Monday. “The Michael J. Fox Foundation is doing whatever it takes to improve patients’ quality of life and deliver a cure to people living with PD, like my father.”

The superhero thriller, set to kick off the summer blockbuster season when it opens in theaters May 1, will premiere at the Mann’s Chinese Theater in Hollywood on Monday, April 28.
