Surefire in the movies

Surefire has released a new video showing clips from many of the movies their flashlights have appeared in. It's pretty interesting to watch, whether you liked the individual movies or not. I've got the first Surefire hand-held I was ever issued years ago and I still break it out on occasion (though I've since replaced it with a newer one for regular use). What flashlight-requiring event stands out in your mind as the time you were most glad you had one – or wished you'd remembered it? More importantly, when is the last time you trained low-light/no-light?
