To answer your questions: Yes the beginning is shot on film. While most people nowadays in Hollywood film on digital/IMAX/4K/etc, Tarantino still shoots entirely on film. The Great Escape is a famous Steve McQueen movie from back in the day. Steve McQueen is a legendary old Hollywood actor, known for doing a lot of his own stunts. (The guy who played Steve McQueen in this movie was also Lt. Winters in Band Of Brothers.) Also, I find that people who play primarily villains and dickbags on screen are some of the coolest and nicest people in real life. Jon Bernthal, Sir Christopher Lee, etc.
The Jophery thing is an outlier where the issue isn't that the majority of people thought he was a wonderful villain who could only play villains, but a tiny minority of people couldn't separate fact from fiction and believed the actor really was a villain and harrassed him (including death threats) to the point he felt he had to retire. While he was still a child.
Yeah, I'm pretty unfamiliar with her outside of the Manson relation. I did learn that her sister was really happy with Margot's portrayal, though which was really relieving and exciting to hear!
@LaVeyanist Manson was the guy who pulled up to the Tate house looking for Terry. Terry was the manager of the Beach Boys. Manson befriended Brian Wilson of the Beach Boys, and they actually recorded one of Manson's songs. However, no credit was given to Manson, and they cut off all contact with Manson. Manson was livid. His plot was to have members of his group go after Terry. After visiting Terry's old house, he concluded that Terry was no longer living there. Regardless, Manson wanted to send a message. Manson ordered Tex Watson and a few others to make it witchy. And they did. They pulled thir car up to the gate on that very road where Rick Dalton lived. Sharon Tate was having a party with close friends. Everyone at the house was eliminated in horrific fashion. They were stabbed multiple times. The group didn't stop there. The next night, they went to another house. It was an event that shocked the country. Suddenly, everyone went from feeling safe to putting locks on their doors. The sentiment of the era was over, and it forever changed Hollywood.
