silent film look

[Job Ter burg]

BCC has the (among others) the Damaged Film effect, which will let you add grain, jitter, dust, scratches, hairs, etc.
BCC comes bundled with MC, and is also part of the 3rd party application bundle that Avid sell (for very little money) on their webstore.

[Matt Mullen]

Job is spot on.

BCC is probably your easiest and best way to achieve this.

If you want to try before you buy you can download the free trial as well.
