Donate to charity for a chance to win not only Avengers: Age of Ultron premiere tickets, but the experience of living like Tony Stark for a day!

As the world premiere of Joss Whedon’s Avengers: Age of Ultron draws closer, Robert Downey Jr. (Iron Man) has launched a pretty awesome contest.

Through Omaze.com, fans can donate a minimum of $10 to the children’s hospice center Julia’s House, and thus be entered into the draw for two tickets to the Avengers: Age of Ultron world premiere.

But the tickets are the least exciting thing about the prize package.

In a video announcing this contest, Downey Jr. describes the fantastic experience the winner can expect:

The winner and one friend will be flown to L.A. on the morning of the premiere. The day in the life of Tony Stark will begin with a breakfast at Randy’s Donuts, then they’ll be taken to indoor skydiving, a helicopter ride over Hollywood, a custom gown/tux fitting, and finally a chance to spend some time with Iron Man himself.

After their fun (but exhausting!) day, the two luckiest humans in the universe will meet up with Robert Downey Jr. for some pre-premiere caviar, where, “We’ll giggle, chat, take pictures. Perhaps even engage in a battle of wits.” Downey Jr. sure knows how to give us what we want!

Basically it’ll be, “the best night of your life, on earth, ever,” in which RDJ is gonna “awesome the crap out of you.”

Um, if that wasn’t a good reason to donate to a good cause (a second good reason, we should say, because it’s always good to give to those in need), we don’t know what is.

Donate now, and good luck!
