West Side Story (2021)
1 deliberate mistake - chronological order

Starring: Ansel Elgort, Ariana DeBose, Rachel Zegler
Continuity mistake: When Tony is below Maria's fire escape, there's a shot of her back with her fingers grabbing the platform. Shot changes to Tony's POV where she moves her hand and changes her grip. Then shot goes back to the previous angle of her still with the same grip.
