Producers of Tom Cruise's latest movie "War of the Worlds" are worried that his new romance with actress Katie Holmes -- which has sparked a media frenzy -- will be damaging to the film.

Polls in the magazines People and US Weekly show that a majority of readers are sceptical about the sincerity of the Hollywood couple's relationship as both Cruise and Holmes have films releasing this month, reports celebrity portal Hollywood.com.

Cruise stars in "War of the Worlds", while Holmes is in "Batman Begins".

But Martin Levy, an executive at DreamWorks, the studio behind the film, fears that the actor's romantic outbursts are stealing headlines away from the Steven Spielberg-directed movie.

Levy says, "You can have so much attention on a particular issue that maybe the movie doesn't get as much attention as it might. It's the topic of conversation for other reasons."
