Producer-director Richard Donner has wanted to do another movie about Gibson's character, police officer Martin Riggs -- but Gibson had little interest in reprising his role, moviehole.NET reported.
Previous studio talks had focused on how to make the plot of the next film more attractive to Gibson. Citing a source, moviehole.NET said the uproar over anti-Semitic remarks Gibson made while he was being arrested and booked has changed his point of view.
The Web site said Gibson might be more amenable now to doing either another "Lethal Weapon" movie, or some other studio projects he has been reluctant to do in recent years.
"It's a sure-fire way of not only staying in good with at least one studio, but the fans, too," the source told the Web site.
