Why do good TV actors flounder when making the switch to film?

Just watched Richard Jewell (decent film, solid performances and direction), and watching Jon Hamm play such a mediocre role broke my heart because he’s one of my favourite actors who crushed it with Mad Men. It could have been played by any no-name and it wouldn’t have made a difference.I look at a large part of his filmography post Mad Men and it’s filled with similar roles. And not just him, even actors like Aaron Paul, Matt Bomer, Don Johnson, and so many more who are way more talented than the execrable roles they get stuck in.Any insights as to why it’s so difficult for great TV actors to transition to film similarly? via /r/movies https://ift.tt/2YF9ypF
