I don't know why some people are acting. Or it's called acting, but you don't see that this person tries to be in character. I mean, guys like Steven Segal... I always think "SHOW SOME FEELING! EXPRESS YOURSELF!!" but no, he's standing there and has only the expression in his face that seems to show he has to make a shit for days. If he doesen't show some feeling, make subtitles, that everyone can see what this guy actually has to feel. A rock, rolling down a mountain has more expression than this guys face.
Now you may say he's just an action-movie star, but that's no excuse. I mean, look at guys like Bruce Willis, Mel Gibson, Kurt Russel, Harrison Ford or Alan Rickman. Those guys can act. You can feel the fear, sadness or anger they can express in the characters they play. They are good examples for good actors in awesome movies, which will never be forgotten.
Just taking someone who can do martial arts, like Segal or Van Damme, doesen't mean they are good actors. No they needed Tommy Lee Jones in "Red Alert", or Raul Julia in "Street fighter" to make it acceptable movies. What where the producers thinking when they casted the actors.
Another bad thing is, when musicans like madonna try to act. Yes, she's the queen of pop and was in a lot of music videos, but that doesen't mean she can act. Maybe they said: "Hmm... who are we gonna take for "Evita"? Let's take Madonna, everybody knows and likes her, so the people don't look if she can act or not."... Suckers!!
Or on the other side. What was Russel Crowe thinking when he started singing? Even as an actor he has a frozen monotone face, so is his voice while he sings. No expression! Singing means to transport feelings to persons by your voice. And when i saw "Les miserables" I wanted to stab my ears with a pencil so I can't hear his "singing" anymore (I know that's a transported feeling, but it doesn't count). No sane broadway musical would give such a guy even a chance to destroy their art.
I mean Putting the wrong people to the wrong kind of art will almost always end in disaster. Even if he's a good actor, doesen't mean he can sing, or if he's a good singer he probably can't act. It's like saying to a painter, go and write a novel. This won't work. That's the way it is.
But, it isn't always that bad. Look at Hugh Jackman, he has potencial in both kinds of art. He can act and isn't that bad at singing. So, there still is hope for some movies based on musicals. You just have to find actors that can sing a bit. And NEVER EVER TAKE RUSSEL CROWE FOR THAT AGAIN!!!!
