Practical effects are physical effects that are created on set, such as explosions, stunts, and makeup.

CGI, or computer-generated imagery, is the most common type of special effect used in movies today. It is used to create realistic images that would be impossible or too expensive to create with practical effects.

Tron was the first movie to use CGI. It was released in 1982 and used CGI to create the light cycle scenes.

Motion capture is a technique for recording the movements of an actor and transferring them to a computer-generated character. This allows the actor's performance to be used to create realistic animations.

The Polar Express was the first movie to use motion capture. It was released in 2004 and used motion capture to create the characters' movements.

CGI is created using computer software, while animatronics are physical puppets. CGI can be used to create realistic images of anything, while animatronics can only be used to create realistic images of living creatures.

King Kong was the first movie to use animatronics. It was released in 1933 and used animatronics to create the character of King Kong.

All of the above. CGI will become more realistic and affordable, motion capture will become more common, and animatronics will become more sophisticated. This will allow filmmakers to create even more realistic and immersive special effects.

All of the above. Special effects will be used to create more realistic and immersive experiences, to tell stories that would be impossible to tell without special effects, and to create new and innovative forms of entertainment.

All of the above. The cost of special effects is increasing, the technology is becoming more complex, and it is becoming more difficult to create original and innovative special effects.

All of the above. The challenges of the future of special effects can be overcome by investing in new technology, by training more skilled artists and technicians, and by finding new ways to collaborate between artists and technicians.

All of the above. The future of special effects raises ethical issues such as the use of special effects to create realistic violence, the use of special effects to deceive audiences, and the use of special effects to promote unhealthy lifestyles.

All of the above. The ethical issues of the future of special effects can be addressed by creating guidelines for the use of special effects, by educating audiences about the use of special effects, and by encouraging filmmakers to use special effects responsibly.

All of the above. Special effects are a powerful tool that can be used to create amazing things, but they should be used responsibly. The future of special effects is bright, but it is important to remember the challenges and ethical issues that the future of special effects faces.
