Write to what you have.

That big car chase though the streets of London ending with a huge explosion abroad the HMS Belfast could be changed to a never before seen foot/bicycle chase ending with a clever fight in someone's livingroom. You have a million and one ideas - one of MUST be a unique way to stage a fight in a small area.

You have a million and one ideas. Doesn't at least ONE of them involve a small group of mates getting into some small time, but interesting trouble in (or near) your own home?

Do you have access to a wooded area? Look at what a few Americans did with a tent, a video camera a few sticks, a pile of rocks and a wooded area.

Do you know of any train tracks in your area? Look and what a few Americans did with a walking journey along some tracks to look at a dead body.

Here's the way to train yourself to think cheap:
very few cast members - challenge yourself to tell a story with less than 8 people.
very few locations - challenge yourself to tell a story using only 3 or 4 locations.
look around you - challenge yourself to use what you have in a unique, creative way.
no explosions or gun fights - challenge yourself to create conflict without fireworks.

The aim of an argument or discussion should not be victory, but progress.

Very good advice, much appreciated!

Instigator is absolutely correct. I suggest taking his rational one step further. Limit yourself to two characters, one location and ten minutes total screen time. Choose one theme, one conflict and one resolution. Study your two characters in great depth (on paper) and reveal thier nature (on screen) through the clearest and most direct means. Create 10 minutes of absolute substance within which the characters and thier choices drive the story and you will be one step closer to becoming a true filmmaker.
