Although many directors now also act, or some actors end up becoming directors and then star in their own films. This way, they have the most control and can better showcase their own thoughts—if they have any. Even if they don't want to express any thoughts, making money is also good; ideally, the producer is also one of their own, and they earn the most when the director, actor, and producer are all from the same family.
However, this kind of director also has limitations. After all, wanting to be both a good director and a good actor while trying to convey their own thoughts isn't impossible, but talent has its limits. Just like himself, it's not just that he's getting older and lacks energy, his creativity isn't as good as it was when he was younger.
A director who relies on talent to make a living, once devoid of talent, narrating stories through mediocre means, will find that many viewers won't buy it.
