'Argo,' a new film based on real-life events, won't be out until the fall, but the trailer has already been released. It stars Ben Affleck (who also directed), Bryan Cranston, John Goodman and a host of actors you've seen in bit parts in many movies over the years.

Set in 1979 during the Iranian revolution, 'Argo' centers around a plan to rescue six Americans who were taken as hostages, but escaped and hidden at the home of the Canadian ambassador.

Knowing that it's a matter of time before they are found and killed, C.I.A. agent Tony Mendez (Affleck) comes up with a plan: he and his team will pose as a Canadian film crew scouting desert locations for a science fiction film called 'Argo.' While in Iran, they have 72 hours to rescue the hostages and bring them back to America alive.

With such a strong cast and a tense plot, a great song was needed to match, and the producers found one in Aerosmith's 1973 classic 'Dream On.' The familiar near-baroque chords enter at the 1:35 mark of the trailer, as Affleck goes to Iran to complete his mission, but soon switches to the climactic final chorus as the trailer comes to a close.
