I know that MGM was acquired by Amazon, but they don't count anymore? Is "Hollywood" meant as a generic reference to the film industry or as the actual location of the studios?
A lot of studios come and go, go bankrupt, change owners, get bought out, renamed, merge with other studios, have their names and IP appropriated by some other company... hard to keep track
Maybe Lionsgate? They don't have the same level as the other 5 but you could make a compelling case that they are a 'major player' in the film industry.
Got all of 'em! Yay! I didn't try it so maybe it works but you should def have Fox (and any other way to type the Fox company name i.e. 20th Century) as a type-in for Disney
Disney owns Fox, not the other way around. Though admittedly, I did forget this and typed in Fox after Disney and scratched my head a bit before I remembered.
