The red band trailer for the forthcoming comedy 'Sex Tape', which stars Cameron Diaz and Jason Segel as a married couple, has been released and it looks like this could be one of the funniest flicks of the year.

The Jake Kasdan-directed film embraces the digital age, and depicts how some people's inability to fully understand the power of today's technology can have disastrous outcomes.

So how does the trailer make this film seem so good?

For a start, 'Sex Tape' features an on-screen partnership that film-lovers have seen before, Diaz and Segel both starred in 2011's 'Bad Teacher', and their shared scenes were among the funniest of the whole movie.

The pair reunite as married couple of ten years, Jay and Annie, who also share two children together. But like many others, they have found family life has dulled their sex life, but in order to find that spark again, they decide to film themselves having sex.

Impressively, the homemade clip is a three-hour long spectacle of several different positions and noises, but once the job is done they both collapse on their front room floor due to exhaustion.

The couple filmed their intimate time on an iPad, and as they are both in a deep sleep the homemade video gets uploaded to Jay's Cloud account. More worrying is the discovery that it has been sent to everyone they gave an iPad to for Christmas, which included a mother, a boss, friends and even their postman.

On realizing this, panic sets in and now Jay and Annie are on a mission to track down every apple device they gave away, as well as figuring out how to remove it from Jay's iCloud.

The trailer shows just how the digital age hasn't been grasped by everyone, as Jay tells his wife, "It went up to the cloud!" Diaz's character replies, "And you can't get it down from the cloud?" "Nobody understands the cloud!" Segel shrieks. "It's a f**king mystery!"

'Sex Tape' will be released on the 25th July in the USA and on the 5th September in the UK.
