Zoe Saldana, Bradley Cooper(ish), Chris Pratt, Vin Diesel(ish), and Dave Bautista in Guardians of the GalaxyFriday, August 1, 9:50 a.m.-ish: Movies based on Marvel comics are routinely, sometimes annoyingly formula-driven. But 10 minutes into Guardians of the Galaxy, I really hope every subsequent Marvel release steals from this one, because all the studio's films - hell, all films period - should open with Chris Pratt doing a Singin' in the Rain soft-shoe to Redbone's "Come & Get Your Love."
