Any Marvel fan would kill to hang out on the set of "Avengers: Infinity War" with Iron Man, Spider-Man and the rest of the superheroes in the upcoming movie.
The video gives a brief behind-the-scenes look at the film being shot -- complete with plenty of green screen and Tom Holland (Spider-Man) wearing a motion-capture suit.
Downey promises "unprecedented access" to the set, including the men's bathroom (complete with Holland joking about leaving his own personal mark on the facilities). In addition to set access, winners will also get to eat lunch with Downey and ask him "all your burning questions."
Fans can learn more about this campaign on Omaze, a celebrity-focused fundraising website. People who donate via Omaze are automatically entered in the contest, plus the bigger the donation the more chances you get to win. You can also earn perks like signed movie photos and collectible toys.
For this campaign, Omaze is helping to raise money for Random Act Funding, a charitable group founded by Downey and his wife, Susan Downey, that backs organizations such as CRI-Help, Atlanta Children's Shelter, Children's Restoration Network and Covenant House Georgia.
"Avengers: Infinity War" is scheduled to hit theaters worldwide on May 4, 2018.
