The Exorcism (out Jun 13) is a decent idea on paper, but events play out as expected, there are few surprises, and the casting isn’t quite right.  Drawing loosely from the making of The Exorcist in 1971, it’s centred on an actor (Russell Crowe) struggling to tap into his character while shooting an exorcism movie.  To complicate matters, weird things start happening on set. Grade: C+.
