Eddie Murphy is not keen on returning for 'Beverly Hills Cop 4'.

The comedian and actor played the protagonist Axel Foley - a hilarious police detective - in the original three movies released in 1984, 1987 and 1994, but said he is not willing to reprise the role unless there is a ''really incredible script'', after Paramount Studios announced they were developing another sequel.

When asked if production on the film had begun, he said: ''Nah, they still trying to get that script right. I'm not doing a 'Beverly Hills Cop' unless they have a really incredible script.''

Last year, the studios announced the franchise's fourth action-comedy instalment would be released in cinemas on March 25, 2016, but with production yet to begin, this has been thrown into question.

Speaking further about the prospect of featuring in the film - which will be directed by 'Horrible Bosses' creator Brett Ratner - the 53-year-old actor said he would not take part in the production just to make money, as he wants to star in something which he thinks people will actually enjoy, following the widespread criticism of the third movie which Eddie himself described as ''atrocious''.

He told Rolling Stone magazine: ''I've read a couple things that look like they can make some paper. But I'm not doing a sh**ty movie just to make some paper. The s**t got to be right.''
