Yes you read that right, Cameron Diaz, Jason Segel, Sex Tape.

Cameron Diaz and Jason Siegel are teaming up again with Jake Kasdan to make a movie called "Sex Tape" as sort of spiritual successor/sequel to "Bad Teacher".

"Sex Tape" is basically about a married couple who decide to spice things up in the bedroom by making a sex tape.

You can probably guess what one of their tricks is, just based on the title of the movie. Another seems to involve roller skates, as shown in this first still.

Whatever happens here, it's probably just the start of this pair's troubles. The script, written by Kate Angelo, has these two making a sex tape only to discover the next morning that the video has gone missing. The rest of the film follows their desperate attempts to recover it before it falls into the wrong hands. This is the official synopsis posted by Sony:

"When Jay (Jason Segel) and Annie (Cameron Diaz) first got together, their romantic connection was intense - but ten years and two kids later, the flame of their love needs a spark. To kick things up a notch, they decide - why not? - to make a video of themselves trying out every position in The Joy of Sex in one marathon three-hour session. It seems like a great idea - until they discover that their most private video is no longer private. With their reputations on the line, they know they're just one click away from being laid bare to the world... but as their race to reclaim their video leads to a night they'll never forget, they'll find that their video will expose even more than they bargained for."

"Sex Tape" opens July 25, 2014 in cinemas.
