Continuity mistake: The second time Hugh Grant writes on the board (not "protagonist" - can't remember the word!) the writing changes between shots - most noticeably a C in the middle, which sometimes has a small loop at the top, sometimes not.
The Rewrite (2014)
Ending / spoiler
Directed by: Marc Lawrence
Starring: Marisa Tomei, Allison Janney, Hugh Grant, Aja Naomi King, Enid Graham, Vanessa Wasche, Whit Baldwin
Keith and Clem go to a meeting to sell Clem's script, which goes well, but Keith realises he actually wants to be back teaching. He returns and apologises sincerely to Professor Weldon for his inappropriate relationship, declaring that teaching has got his hooks into him, and she grudgingly gives him a second chance. He talks to Holly, they admit their interest in each other but agree to wait until the end of the semester when he'll no longer be her teacher. He returns to class, keen to help his students finish their third acts.
