If you know Daniel Craig only as James Bond, “Queer” is liable to throw you for a loop. In this new film from Luca Guadagnino, which premiered at the Venice Film Festival on Tuesday, Craig, 56, plays a drug addict whose sexual escapades and heroin use are filmed with matter-of-fact candor. But if you knew Craig even before he was pressed into Her Majesty’s Secret Service — when he was still an up-and-coming young actor who appeared in risky, sexually explicit films like “Love Is the Devil” and “The Mother” — then you might guess that “Queer” is much more in line with his sensibilities than some of the big studio fare he’s made recently are.
