A psychologist who begins working with a young boy who has suffered a near-fatal fall finds himself drawn into a mystery that tests the boundaries of fantasy and reality. The trailer makes the film look like a nifty little psychological thriller with shades of the terrific movie Vanishing Waves thrown in for good measure. Actor Max Minghella wrote the screenplay for the film based on the bestselling novel, and this looks to be a promising feature from him and director Alexander Aja (Horns). Hopefully it all comes together and lives up to this trailer. Jamie Dornan, Aaron Paul and Sarah Gordon make a great cast.

After scoring a sleeper success with 2012’s “Sleepwalk With Me,” which adapted his solo stage show about toiling on the standup circuit, writer-director Mike Birbiglia stretches out a bit — but not too much — with the accomplished seriocomedy “Don’t Think Twice.” Like its predecessor a pleasingly naturalistic insider’s view of life on the lower rungs of showbiz, this more ensemble-focused piece is also somewhat autobiographical, as it draws on Birbiglia’s background training and performing with improv groups. But here a fictive scenario develops in which one member of a longtime improv troupe suddenly wins the comedy lottery of a cast gig on a “Saturday Night Live”-type sketch show, throwing those colleagues left behind into turmoil. This realistic but not excessively downbeat portrait of fame striking a lucky few — and missing everyone else — should build on “Sleepwalk’s” fandom to decent niche returns in various formats. Friendship revisited. The cast including Kate Micucci, Chris Gethard, Gilian Jacobs and Keegan Michael Kay.
