Are you planning on playing the etude yourself?
Like the second idea much better -the first sounds a bit hopeless and depressing -I always think an idea works better when there is a problem which CAN be solved -if your nemesis is a super powered alien -you stand a chance in hell of beating it -
I've had a couple other ideas with that prelude but I feel like those would be hard to execute as well because I can't find a girl to be one of the characters for me.
"Hey, you're pretty. I'm making a film. Would you like to be in it?" has a long history as one of the most successful pickup lines ever.
