find the number of ways in which 5 men can watch 4 movies such that each movie is watched by atleast 1 person?

Each movie can be either watched or not watched. There are 4 movies and 5 friends. So each movie has 5 choices that it can be watched by 1 person, 2 persons,3 ,4 or 5.
So each movie has these 5 choices. So required number of ways would be 5^4.
