A Star Is Born (2018)

Factual error: Towards the end of the movie when Ally is in her hallway looking at Jack's old concert tour posters hanging on the wall, the poster closest to the camera says "Washington State Fair" and a 2011 date. Unfortunately, that fair did not get that name until 2013. Before that, it was called "The Puyallup Fair" (officially named the "Western Washington Fair"). Locals still call it "The Puyallup Fair" to this day.

Revealing mistake: Jack and his brother are driving in a truck and the speedometer shows zero.

Continuity mistake: The first time we see Jackson rehearsing, his brother comes to the first row to talk to him, always with his right arm down. There's a brief shot from a different angle where his arm is suddenly up. Then back to the previous angle where the arm is lowered for the rest of the scene.

Sacha

Trivia: Sonal Chapelle, who portrays Frankie Stone, is the real-life daughter of Dave Chapelle, the actor who portrays her father "Noodles" Stone.

Trivia: The dog that Ally gives Jackson is actually Bradley Cooper's own dog, Charlie.

Jack: Hey!
Ally: What?
Jack: I just wanted to take another look at you.

Jack: Look at me. All you got to do is trust me. That's all you got to do.

Jack: Maybe it's time to let the old ways die.

Question: How did Charlie get outside at the end of the movie? Jack made sure he was inside then after Jack closed the garage door Charlie was lying in front of it?

Question: At the beginning when they meet she sings a few lines of Shallow, then presumably the next day at his show he brings her onstage, and they sing the whole song with the band and all...how is this possible with zero rehearsal time?
