Read somewhere else that there's a difference between "great actor" and "movie star".
Burt Reynolds was undoubtedly the latter...
I'd definitely agree with that. Some people, like a star, light up a room when they enter.
For example, I don't think any amount of Acting school training could help someone replace Jim Carrey as The Mask or Ace Ventura*. Some actors can walk onto screen and simply dominate proceedings.
Michael Caine is a movie star. I know he gives acting lessons but I don't think he ever did anything more than read lines in the way he always reads them. Clint Eastwood was another. They got covered in stardust at an early age
* I've always thought Carrey's performances were underrated but genius slapstick always has been.
