Film Producer

As I am a Producer for this music video I wanted to know exactly what a film producer really does, and also what I need to do to be successful for this role.
Well for a start I wanted to know what the producer does...The film producer is the only person who is involved in the making of the film, from the very start which would be the idea to the end which would be the delivery, they are also the person that makes things happen, they organize, protect and supervise the rest of the production crew.

For this Job I will need a pre production checklist which will include:
Log Sheets: Details of production shot by shot.
Release forms: Permission for you to film a person.
Directions to locations: So people know where it is.
Shooting Schedule: A plan of each shooting day for film.
Props List: A list of props used in production.
Location permits: Permission to film at certain locations.

I may also need:
Food and drink for the crew: It will be a very long day of filming and the actors could get bored or hungry throughout filming so a snack and drink will keep them happy.
Make up: For Actors/Actresses ready to go on set.
Costumes or wardrobe: Change of clothes for next scene.
Cue cards: For the crew members to know when to come on and off set
Weather check: You need to know the weather forcast otherwise you could have bad weather on the day of filming.
Calling of all participants to confirm places/times: You will need to get contact with the locations you have booked to see if you can go on that day to film and to see what time they would like for you to show up on the day.
