Once upon a time, making a sex tape was a much less risky business - mainly because the "tape" part was literal rather than figurative. The worst thing that could happen would be an unscrupulous friend stealing the tape (à la Trainspotting) or a few more physical copies being made and handed out.

Then high speed internet came along and made the whole endeavor a lot more dangerous. In Sex Tape, the raunchy new comedy from Bad Teacher director Jake Kasdan, Cameron Diaz and Jason Segel play a nice, respectable suburban couple who wear sensible sweaters and go on outings to Bed, Bath & Beyond. Their family life has led to a stagnant sex life, and so Annie and Jay decide to spice things up by making a sex tape - using their iPad.

It only takes a little meddling from the semi-mystical entity known as the Cloud before Annie and Jay's intimate video ends up in the hands of everyone to whom they gifted an iPad for Christmas - including parents, small children, co-workers, friends and the mailman. Since nothing is ever completely gone from the internet, Annie and Jay set out on a mission to destroy every copy of the video before it can be uploaded for the entire world to see.

It's not easy to convey this kind of story while maintaining a green band, so the new trailer for Sex Tape is largely comprised of footage that was included in the red band trailer, minus a lot of swearing and a scene of Annie snorting cocaine with her boss (Rob Lowe). The humor is a little spotty and some of it falls flat, but who knows, maybe they're saving the really good stuff for when the movie comes out.

One downside to Sex Tape is that it could end up becoming very dated very quickly if iPads and Siri go out of style. After all, give it another five years and we'll all be accessing the internet via chips in our brains and deleting compromising videos with a single thought. Probably.
