I want to be able to create decent hollywood style high frequency tones- Sustained bell,glass or metal shimmering layers in my sound design projects.In the past I have mainly used stock effects for these but I really want to start creating these from scratch.I have tried countless times but not had any joy.

Besides granular plug-ins, Waves' Enigma can be useful for this kind of stuff. Yes, Enigma modulates back and forth between two sounds, but you can "pause" it when it's got the tone you want. When you do, it will hold the sound it's creating until you release it (turning into its own form of granular synthesis). It's great for creating a sound that needs some movement into a sustained tone.
bow things, reverse things. explore various cymbals, bells like a crotale, singing bowls, wine glasses, etc. get a big bow and bass rosin. layer, verb, reverse, all that fun. i'm also a big fan of the ebow, resonating strings of various instruments.
I am actually finishing up a library of those kinds of suspenseful glass and metal sounds right now. I used a lot of crystal wine glasses, bowls, saws, sheet metal, etc. As mentioned above, bows are very helpful. I also got a ton of good material playing with digital and analog feedback.
