Interestingly enough Rockstar did produce a movie, 2004's The Football Factory, about British soccer hooligans, no I haven't seen it either.
I have no idea whether it had a theatrical release in the UK, but it certainly didn't in the US, I don't know if it got a release in the US at all, even direct to video.
I really, really hate to think the good days of Rockstar are already done, especially because they went from releasing so many different games in the 2000s to a grand total of... 5 in the 2010s.
The Rockstar branding was first used for GTA2 in 1999, last Rockstar game to have the Housers involved was RDR2 in 2018, so it didn't even make it to 20 years, which is sad.
But if the Housers are gone then it's over, they are Rockstar games, I just wish we could have gotten just one last game after RDR2 though, for me a big missed opportunity is a Bully 2, I would have loved to see that.
Here's a fun fact for you, you can see the Houser's mom naked, she's actress Geraldine Moffat and appeared in a nude scene alongside Michael Caine in the movie Get Carter, that might be embarrassing, but if your mum has to be naked then being naked with Michael Caine has got to instead be an honor.
