Planning for production - Choosing actors

There are going to be many considerations to take when choosing actors to play different roles in our film. First of all we have to be realistic when choosing who we can get to act in our film, it would be very unrealistic for us to attempt to get a established actor (E.G. Daniel Radcliffe) to take part so we are going to have to find people relatively unknown that fits the role we want them to play. That brings me on to my next point, when choosing actors we have to make sure they fit the role as there is no point in putting so much time into producing a good film if the actors we choose do not fit the role we want them to play. Lastly we have to ensure that we choose people that are able to work together well and get the job done well by showing professionalism as if not it might effect the end product. These, as well as others, are all considerations we're going to have to take when making the film as they can and will have a big impact on the outcome of the final product.
