HMMM..
Are there things we should know?
That sucks.
For what it's worth, I thought they didn't cast his character well in 90210. The guy looked damn near 30 years of age and was playing the role of a high school student. I believe Perry was 23 when they first started filming 90210, but age wasn't kind to him.
Likewise, the Ziering guy looked terrible as well and in no way resembled a high school student. Here's a picture of Ziering from when he was in the show.

Certainly that had to be at the end of the first run? I mean him and Luke always did seem miscast and older than their characters, but he looks 35+ there. I didn't watch the last few years...did they ever go on to college, or did they always pretend they were stuck in time and in h.s. til the show ended?
