Continuity mistake: When Riff tosses cans at Tony, Tony's right arm is raised. A shot later it's lowered.
Continuity mistake: When Tony lies dead, his head is facing right or left between shots, no continuity whatsoever despite Maria not touching him.
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.
Continuity mistake: When one of the Jets jumps on the pickup to unload all the veggies and watermelons, the car on the left changes between shots. Also, when he is about to unload the veggies, the pick-up is approaching a blue squared van on the left. The shot changes, and the van is further away.
Answer: No, she doesn't, but Tony is shot and killed.
