A whimsical, half-formed paean to criminal fraternity, Stand Up Guys brings together Al Pacino, Christopher Walken and Alan Arkin as retired gangsters who, against the backdrop of an impending assassination, reunite for a wild night of drugs, booze and women, with a sprinkle of reflection on aging and loyalty. Its synopsis may summon contemplations of a gangland Grumpy Old Men, but the first produced screenplay of playwright Noah Haidle, unfolding over the course of one night, cycles through too many haphazard and improbable set-ups to amount to anything more than a collection of signed offer sheets in search of a movie. This is the shaggy, cinematic equivalent of a greatest-shtick collection, dragged into watchability only through the lively interplay and accrued goodwill of its leads.
