It (1990)

Continuity mistake: When they are in the library after they found out Stan committed suicide, it shows Beverly stand up but when it cuts back to her she is sitting down and stands up.

Bill: He thr-thr-thr-thrusts his fi-fi-fists ag-ag-against the pos-posts and...
Ben: He thrusts his fists against the posts and still insists he sees the ghosts. That's all it says over and over.
Bill: Th-th-thats w-w-what m-m-my m-m-mom g-gave me t-to h-help with my st-st-stutter.
Richie: I hate to tell you buddy, it ain't working.

Trivia: Tim Curry admitted that while he enjoyed working on the film, he was ultimately disappointed by the finished product, mainly due to the ending. He felt the final creature (a massive spider) was poorly executed and a massive let-down, and lacked any sense of fear or suspense.

Question: Tim Curry is said to appear as two different characters, Pennywise and Richie's boss, but I couldn't see him as the second. Where does he appear?
