The 90-second film, So what are you doing?, will be shown from Friday alongside Stanley Kubrick's last film, Eyes Wide Shut, at a major London cinema.

Initially it will run for two weeks at the Warner Bros cinema in Leicester Square, but there are plans for it to get a wider airing.

Eyes Wide Shut, a semi-erotic study of marital jealousy starring Nicole Kidman and Tom Cruise, is expected to attract a huge audience.

Produced for the organisation Women Against Rape and directed by Michael Massey, the date rape film is part of a campaign to highlight the issue and push for more action to tackle it.

The film presents a series of brief slow-motion scenes from a date. There are no words, only music and short statements about the date punctuate each scene:

"You call". "You meet". "You drink". "You dance". "You flirt". "You leave".

"Nightcap, coffee?". "You touch". "You kiss".

"She stops". "You don't".

The film then shows a picture of the man holding the woman down.

"What are you doing?" it asks.

The audience is then informed that two out of three rape victims know their attacker.

Trevor Beattie, of creative agency TBWA, which produced the film with GGT Direct, said: "If [the film] causes mass male nervous fidgeting in the corridors of power as well as the cinema audience we will have succeeded."

Increase in date rape

The number of alleged cases of date rape - rape by a known attacker - has risen sharply in recent years.

The Home Office blames this for a fall in conviction rates for rape over the past 12 years.

Convictions are more difficult in date rape cases

It says it is more difficult to secure a conviction in a date rape case because it is often a case of one person's word against another's.

The government has appointed a specialist group to review rape legislation to see if there should be any changes to the way the crime is defined.

Proposals being studied are said to include shorter sentences for "date rape" than for people attacked by strangers.

However, Betty Moxon, chairwoman of the specialist group, said evidence from victims did not suggest being raped by a person you know was any less traumatic than being raped by a stranger.

Victim Support and Women Against Rape back her views and oppose a separate offence of "date rape".
