I feel compelled to mention once again that I CAN MAKE A PRETTY FANCY POWERPOINT PRESENTATION.

That's great! I would have liked some frantic clawing at the briefcase as the end or a head bouncing toward the camera, but it was pretty cool.

You could have done more of a punchline by having him see another person and call for help, and that person shows that he or she is also cuffed to a briefcase. That person explodes, and our protagonist becomes frantic.

Maybe he notices two boulders butted together and swings the briefcase into the crevice so that the stones protect from the explosion when the bomb goes off.

Dazed but out of immediate danger, he stumbles to a Lamborghini parked nearby.....

I'm not going to kid you, it starts to get a little expensive at that point.

I agree: horrible tragedies belong in Australia. Sorry, Australia. It's science.

Spoken like a true wise man.

...and criminally negligent personal trainer.
