“Discover how little you know about the people you know,” suggests the slightly sinister tagline to Jason Reitman’s upcoming Toronto world premiere.

Men, Women & Children stars Ansel Elgort – he of The Fault In Our Stars and Divergent – alongside Jennifer Garner, Adam Sandler, Rosemarie DeWitt and Reitman regular JK Simmons.

Heavy cast, heavy-looking yet worthy-sounding drama about sexual frustration.

We see people obsessing over social media and personal technology, typing messages, looking up, looking away, looking concerned.

The Toronto world premiere is set for September 6. Paramount will distribute in the US.
