Hi guys,

Im trying to make a scene where a guy gets pelted with rocks, from pebble sized to small boulders. Could anyone help me create this effect or even come up with an alternative.

Thank you in advance

Is he a good friend? If not... just do it live...

The movie "The Lottery" is a perfect example of how a kid is stoned to death, but they never actually show him getting hit, try to mix in shots of rocks being thrown, then him dying, but them never actually hitting him.

Or you could just let him take one for the team.

If you have a green screen, you could take pictures of different rocks in different positions(tumbling throught the air) and then take out te green with something like Adobe Premiere Elements or CompositleLab and then insert them into the movie and have the actor flinch alot so you can time the rocks.
Hope this helps!

Styrofoam, dude. Hollywood has used styrofoam to make rocks since the dawn of time. You can, of course, buy pre-made foam rocks, but its pretty easy to make them yourself. A blow-torch makes quick work of creating natural rock shapes out of blocks of foam, a bit of painting and there you go. There's loads of instructional advice online on crafting foam rocks yourself, as well.

Keep in mind that they will bounce a lot more than actual stone, and you will have to pretend they are heavy when throwing them to sell the illusion, but it is certainly a technique that works.

Styrofoam mixed with a few inserts of real rocks/stones is all you need.

The styrofoam rocks hit the actor, the real rocks hit the ground to add realism.

Throw from like five feet away. You know, people didn't stand a hundred yards away to hurl rocks. Then again, if they're really chucking the rocks, they're liable to miss their target (namely, anyplace other than the actor).
