Shia LaBeouf went from starring in blockbusters to being cast out from the Hollywood system, mainly due to his multiple arrests and his own personal demons.
Because he is a-hole and difficult to work with.
People like to make it sound like only women actresses suffer from being labeled "difficult to work with" and stopped getting work. But we see that it happens with men too. Shia LaBeouf, Ezra Miller...
And it all happened before his ex-gf accused him of abuse. He was this young teen star who was bringing money to producers. Then he became weird and dark. Was throwing tantrums on sets. Was attacking his partners in movies.
And aged out from being "cute teen" to "gross adult". So they stopped offering him good roles.
His main problem is that he is raging entitled a-hole. And reading all those reports from that article I feel like all his costars hated him. I didn't even knew about some. Alec Baldwin one, Scott Eastwood.
