Hiring by Movie Studio

MGM's contracts were legendary, so it's likely legal.

If such contracts weren't legal, they could be overturned in court, which would be expensive for the studios, so they (and the actor & their agent) would surely have lawyers look them over?

roger and Tes yeux noirs-

Thank you.

I think the practice was legal and was called the "studio system" until a major government lawsuit forbade the practice. But when I look it up and only find that the studios and theaters have to be separate.
