The chance to ride with DiCaprio sold for 1.2 million Euros ($1.5 million) at the amfAR Cinema Against AIDS charity Thursday night (May 23), according to the Hollywood Reporter. The prize was listed as a "once-in-a-lifetime trip to space with a mystery guest" in the auction booklet, and the mystery guest's identity as DiCaprio was not announced until after the sale. The event took place at the Hotel du Cap-Eden-Roc during the annual film festival on the French Riviera.

 

Regular tickets aboard Virgin Galactic's SpaceShipTwo sell for $250,000, and already about 550 people have paid in part or in full, despite the fact that the vehicle hasn't yet flown to space. The first manned flight to the edge of space is expected by the end of this year, though, and commercial passenger trips could begin in 2014, Virgin Galactic's billionaire founder Sir Richard Branson has said.
