The logic is a little off as mention bye @buran.
This is a quick and dirty fix,also your del is function not working for me.

if __name__ == "__main__":
    open(FILENAME, 'a').close()
    main()

Output:
C:\code
λ python movie.py
COMMAND MENU
list - List all movies
add  - Add a movie
del  - Delete a movie
exit - Exit the program

Enter Command: add
