how to delete GIGS of movie clips

I've been searching online through the forums and on the apple support pages and this problem has perplexed me to no end

I've got a whole season of kids lacrosse footage that I'm wading through and now that I'm done making a highlight movie my hard drive is nearly full of movie clips and I can't figure out how to (cleanly) delete them.

I do know that in iMovie I can right click on a clip and ask to have it revealed in finder and then move it to the trash. But do I have to do that for every single clip???

I also know I can right click on a clip and have either the selection or entire clip "rejected" but it is still taking up space on my hard drive.

Surely there is an easier way to narrow down what's on my hard drive without having to delete every clip one at a time. I don't mind doing that but I still want parts of those clips.

This is really driving me nuts.

Tks for you help...

Not sure but does holding down shift+dragging on multiple files work in iMovie?

i haven't had any luck with "dragging" but you can shift and "click" to select multiple files.

Highlight your movie clip then go to File > Move to Trash.

As per MuckChiller, you can click on the first one you want to delete, then hold down 'shift', click on the last one you want, then Command>Delete
