Unit 2: Foley Effects

1.  Why can't actors/stuntmen and actresses/stunt women do their own fight scenes and actually make contact to make it look real?

Due to the camera changing shots every so often, the camera makes the fist get in the way making it look like they actually made impact. The sound and impact get added on later during post production.

2.  Why can't actors/actresses actually smash a glass to have the real effect?

Getting a glass that looks like that is very expensive to buy. Also cleaning the mess up would take sometime holding up production.

3.  Why can't actors/actresses use real explosions?

That would be incredibly dangerous for everyone in production. So for everyones safety they just make the explosion CG.

4.  Why can't movie crews install a real phone that actually calls the actor/actress?

The phones are actually fake props used instead of real ones. Also if they used real phones the phone ringing the actors would be in the background of the set so it would be distracting.

5.  Why can't actors/actress attach microphones to their ankles to record the actual sounds? 

The background sounds would be too much and would take an incredibly long time to edit out. Theres also the possibility that the microphones would be broken mid-shoot

6.  How do they know what all these science fiction sounds are supposed to sound like?

No one actually knows what the sounds for the sci-fi movies actually sound like so the movie makers just make up the sounds. Take for example the iconic T-rex roar from jurassic park, scientists still haven't found out what an actual T-rex sounds like so, the film crew just mixed together the sounds of a baby elephant, a tiger, and a whale to name a few. 

7.  Why must they recreate every single sound for film, animations, and games?

They do this to make the sound as believable as possible to the audience. This is also done to make sure there are no errors in production.
