Did computer really helps in making spacial effets in flims

yes my friend in today's technological advancement Norcross special effects which we see in the movies are made on the computer. Not only because they are very cheap but also because they're very safe. Things like explosions and high jams where all is very difficult to do and had a risk element always with them. But with the advancement of computers now it is very easy to add any kind of disastrous effects to the movie without taking any risk. And because of this presenting such things are now very easy.

You can create many effects including 3D effects on computers. It is like never been before and is getting better over time.

Yeah I think so films are depend only on Computer.Computer plays a important role in making movies specially of Hollywood.

computers changed the movies today! unlike in the past where people wear costumes just to get the speacial effects. now even 1 computer can make a whole movie.
