Jeremy Sisto
When I first saw this movie, I thought that whoever played Roberto was really believable and convincing. Then, for years, I completely forgot about it.
Then came 'Six Feet Under'. For some odd reason, the slightly insane brother of Brenda seemed familiar, but I couldn't quite tell why. Convincing and believable, sure, but where had I seen this guy before?
Tonight they showed 'Grand Canyon' again on TV. Haven't seen it for a couple of years, but it's one of my favourite movies. Suddenly I jumped out of my seat, shouting "that's HIM! that's that guy from that... dead-people-show!", probably scaring nearby people. I'm not eloquent when startled.
Now, aware that it's Jeremy Sisto, I watched Roberto very closely. And yes, his acting is top notch, even for the mere kid he must have been at the time. It's like his uncomfortable teens are really showing. Or maybe it's just very clever writing and directing.
