QCA Film Quickie: The Mysteries Of Pittsburgh

The Mysteries of Pittsburgh, based on the 1988 Michael Chabon novel, played at Sundance this year and will get limited release at the end of the month.
Art (Jon Foster) is stuck in Pittsburgh for the summer with his off-and-on girlfriend (Mina Suvari) and his overbearing mobster dad (Nick Nolte). His mundane life sucks until he meets Sienna Miller and her lusty criminal boyfriend, Cleveland (Peter Sarsgaard). As the summer heats up, so does their association, eventually drawing once straight-laced Art into a lover’s triangle.
We’re not crazy about the music and it doesn’t exactly look like the 80’s, but we’re happy about the prospect of man-on-man sex. Has anyone who’s seen the film wanna share what happens (regarding the gay sex)?
