The Saints Row film will be formally announced next month.
But the plan to have the movie release at the same time as Saints Row 3 - set for launch some time before March 2012 - is in a state of flux.
"I'm not going to comment on their timing," THQ CEO Brian Farrell told Gamasutra". "I can't speak for the people in Hollywood. [But] this builds our brand at no cost to us."
In June THQ said a "major filmmaker" will be involved in the film.
At the beginning of last year, rapper 50 Cent said he was optioning Saints Row for a movie. Fiddy had his own game Blood on the Sand published through THQ.
This is all part of THQ's plan to "transmedia" its properties. As well as the Saints Row film there's a two-hour TV movie based on Red Faction and a Homefront novel in the works.
