Oh okay, lol. Yeah the CGI that surrounded them in the Chrono Bowl was so noticeably different that I have to assume it was a deliberate stylistic choice, however misguided it might have been. I can't think of any other explanation for why they'd use such obvious CGI for actors that were right there in the movie (his parents, etc.) Obviously it doesn't mean that the choice *worked* but at least I can see where they were coming from as opposed to them trying to make it look real and failing spectacularly, lol. For whatever reason timelines that circle the Chrono Bowl just look super cartoony until you enter one.
Poor Ben. His suit got totally upstaged by Keaton's and his Bruce got totally upstaged by Clooney, lol. At least he got a cool bike.
