Actor Ryan Reynolds is giving fans the opportunity to step out on the red carpet with him at two of his upcoming movie premieres to raise money for Michael J. Fox's Parkinson's disease charity.

Reynolds is auctioning off a pair of dates for X-Men Origins: Wolverine and The Proposal, with the highest bidder for each sale winning a night out on the arm of Scarlett Johansson's husband. All proceeds from the auctions will benefit the Michael J. Fox Foundation for Parkinsons Research.

Reynolds is the celebrity spokesman for Team Fox, the fundraising arm of the charitable organization, and it's a cause close to the star's heart - his father also suffers from the degenerative brain disease, reports People.com.

Back to the Future actor Fox has battled the illness since 1991.
