Friday, 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."

THE HANGOVER PART III

Not long into The Hangover Part III, our mishap-prone heroes portrayed by Bradley Cooper, Ed Helms, and Zach Galifianakis are seen sipping beers at a karaoke bar, discussing the best way to handle their latest mess initiated by Ken Jeong's eccentric gangster/eternal thorn-in-the-side Mr. Chow. Though this might constitute a minor spoiler, the casual drinks consumed in this scene are, to my recollection, the only drinks - indeed, the only judgment-impairing substances of any kind - consumed in the entire movie. That makes director Todd Phillips' outing a Hangover without hangovers. In the end, it's also a Hangover without The Hangover.

NIGHT AT THE MUSEUM: BATTLE OF THE SMITHSONIAN

Night at the Museum: Battle of the Smithsonian is to its precursor what Ghostbusters II is to Ghostbusters: the less-novel offering, sure, but a follow-up of surprising wit and great throwaway touches, and one that, in many ways, improves on source material that was pretty terrific to begin with. Despite its titular locale, no one is going to mistake director Shawn Levy's adventure comedy for a work of art, yet when this follow-up is really working - which is surprisingly often - it provides a giddy, giggly rush, and it's filled with comic bits that you could probably watch three or four times in succession and laugh at every single time. The movie is scrappy, silly, and a load of fun.
