Hi guys & gals!

I will have to finish it by this weekend!
If u have any idea for this topic, pls give me some!(as soon as posible)
Thanks for ur help!

Oh, too many things to do to make a film successful! Here are the main factors that make film successful (In recent time)
1. The advertisement and the pre-activities before launching the movie. for example: the cost of advertisement for Titanic, Shrek, Harry Potter, Lord of the rings...
2. The famous casting (Athough it isnot always the case) make the movie known and attract the attention of public, mass media....for example: Ocean Twelve, Pirates of Carribean, Mission Impossible ...
3. The heavy investment on making the movie. The fact that most of the famous movies nowadays require a huge sum of money to produce, taking the example of Titanic, Star war...
4. The unified and attractive thread of story: that make the film become interesting and make the movie-goers remember and want to keep tracks of the next parts, therefore so many movies are produced in series like Mission impossible, Matrix, Lord of the rings, Star wars, Pirates of Carribean...

and so much more.......
Have fun
