As you may know, an "A-lister" refers to a celebrity who is at the top of the food chain. When it comes to movies, television show, brand campaigns, fashion shows and more, A-listers are often approached first. Even better, these celebrities also tend to command a lot more money. For instance, A-list actors can command a $20-million paycheck for a single movie, even more.

In Hollywood, A-listers can typically be classified into two types: jerks and sweethearts. Having experienced incredible success, some A-listers like to stay modest and humble. These are the ones who remain nice and professional to their co-workers and fans. On the other hand, there are also a lot of A-listers who prefer to be rude to everyone. Here are some we found, along with two A-listers who are low-key sweethearts.

17 A-List Jerk: Tobey Maguire

It seems Tobey Maguire prefers to be called Tugboat Maguire. And so, it seems a fan upset him badly when she didn’t refer to him in this manner. According to a report from Clickhole, Maguire screamed at the fan saying, “I’m small but strong, just like a tugboat, so call me fucking ‘Tugboat Maguire.’ How hard can that possibly be?”

As some fans have come to find out, “Batman” actor Christian Bale doesn’t really care for fans.

5 A-List Jerk: Robert Pattinson

It seems the ‘Twilight’ star has some not-so-nice things to say about the fans of the successful franchise. In fact, Robert Pattinson once remarked to Interview magazine, “Twilight has its own fan culture that existed from day one. And in an intense way that didn't exist before. Sometimes I ask myself what these masses of people do the whole day. They sit in front of their computers and comment on anything having even remotely to do with Twilight.”
