Every role he plays is wonderful. Boston Legal! The secretary! Blacklist! IIRC he was in an early Molly Ringwold teen flick too.
He was a staple in some of the early Brat Pack movies in the 80's and was in a number of John Hughes classics. He always played the rich jerk.
Spader went to Phillips Academy, so he had already done a lot of research when he played those guys.
Less Than Zero is an underrated movie, imo. I saw it again 10-15 years ago, and I thought it held up well. I have fond memories of
Wolf too, but I haven't seen that again since it was in theaters (and I remember the SFX being a little cheap-looking, even then).
Stargate was an almost startling swerve for Spader, playing the nerd (and I would forgive anyone who'd completely forgotten that Spader was in that movie, after Michael Shanks took the role from him - rewatching the movie years later, it felt like Spader was the one playing someone else's character).
EDIT: I always forget that John Hughes didn't actually direct
Pretty in Pink. It was Howard Deutch, who also directed
Some Kind of Wonderful. Hughes wrote both of those, so I think it's fair to call them "John Hughes movies." In fact, I think you could use "a 'John Hughes movie'" even more broadly than that, to describe a whole subgenre, whether Hughes was actually involved or not.
10 Things I Hate About You, maybe?
Can't Hardly Wait? There was an Elisabeth Shue movie I remember liking,
Adventures in Babysitting, that had kind of a John Hughes-adjacent vibe. (Hey, this is funny: Anthony Rapp, from
Rent and
Star Trek: Discovery, played one of the kids in that movie.)
Hit and Run on Netflix is an excellent spy thriller series.
I've been looking for a satisfying spy story. I tried
Condor and
Treadstone, but neither could hold my attention for long. I also had access to
Berlin Station while I had Epix, but when my 99¢ month expired I didn't want to pay full price for another, and I never got around to it. I've also heard good things about
The Bureau, but I don't have the sub for that streaming service either.
