Ananova:

The second X Files film has had its UK premiere in London's Leicester Square.

Among the stars at the screening were David Duchovny and Gillian Anderson, who reprise their roles as Mulder and Scully in The X Files: I Want To Believe.

Anderson admits the movie has suffered in the shadow of the all-conquering new Batman film, The Dark Knight.

BBC Online reports she said: "It's had a bit of a rough time in the States. It's opening against one of the highest grossing movies, Batman.

"People in the States are so used to lots of CGI, action and sex and we don't really offer a lot of that in this film."

I Want To Believe took £5.1m in North America on its opening weekend, and is released in the UK on Friday.

The first X Files movie, released in 1998, took a total of £94m worldwide.
