Probably right. However were they really going after TC the actor? Or just that he was cookoo?
They were going after both because they figured him being crazy would attribute to box office bombs and it did. Look man, bottom line, his flicks have been meh as of late and the box office return hasn't been what they used to be for him, something he himself acknowledged in an interview he did last year when he talked about after earth and juxtaposed it with his dad dying. Especially since when people talk movie stars and success, they're talking about domestic numbers, not international and domestically, Will hasn't been the same dude he used to be. Take After Earth (please, *rimshot) it only made $60 mil US..that's not good man. MIB 3, for a movie that costs at least 220 to make (and the rumors say it costs at least 300) to only make $178 in the US isn't a good look either.
Terminator Genysis was a flop here but cleaned up overseas but when people talk about it, it's still with the stench of it being a flop because we're a very self-focused country breh. And those production budgets you're citing don't include marketing budgets, which is also a factor. So while MIB 3 may have a listed production budget of 220, you can say the actual costs (marketing, distribution) is double that. So the marketing campaign for MIB 3 alone was probably 100 mil so it's at least 320 or maybe a tad more.
