“Wow” indeed, Matt Damon. Soderbergh has officially “retired” from filmmaking after the release of his latest flick “Side Effects” (which is totally fine but not as good as either “Haywire” or “Magic Mike,” which is seriously in danger of being remembered as his best movie. It’s so good, you guys), but he’s still the busiest bee in the Hollywood hive, and his Liberace movie with Michael Douglas and Matt Damon is, uh… coming out (sorry) next month on HBO. Given that Soderbergh can do more with the per-ep budget of “Game of Thrones” than most directors can do with $100 million, it’s very reasonable to have high hopes. Here’s a terrific trailer for it.
