The IMDb stands for internet movie database and allows us to see what the most successful films are and basically anything we desire to find out about films in general. The site allows you to see what people have been involved with for example what they have acted in, soundtrack, write etc. This is a good way to see how successful people are and what type of films they have been in for example a horror film might not be interested in casting someone who has only been involved in romance films. This could also help casting directors choose actors and actresses for films as they can find out what films they have previously been in and what type of character they are most successful at if any.
