I suppose we all loved those kind of sci-fi movies where terrible things came out of swamps and came to Mars. And there's usually some poor girl. All the guys are trying to desperately handle levers and saying, go to something or other.
The little song and dance number at the end - that's me, my voice, howling out. It was a new experience for me. I've never sung before and I've certainly never sung on screen. I think I sung on stage when I was 13 and for some reason nobody's asked me to try it again since.
