Ah, "Cruel Intentions." Memories...
I stupidly thought the TV show would be a dead cert for a one season pick up due to good buzz, Sarah Michelle Gellar being onboard, the movie continuing to get positive coverage after all these years... was genuinely surprised when it ended up dying a slow, drawn out death. Aside from Reece Witherspoon's character being recast, the likes of Selma Blair, Eric Mabius, Joshua Jackson, Sean Patrick Thomas, and the incredible Christine Baranski, could've all potentially guest starred down the line with it being a follow up to the film as opposed to a reboot.
Doesn't seem to happen so much these days, but I live in hope the actual pilot might find its way online someday. Though the script would be nice, too, I guess.
