1. Get the biggest wooden stick you can possibly find.
2. Twine some barbed wire around it.
3. Go stand next to a concrete wall.
4. Smear some glue on the concrete wall, and scatter some broken glass in it.
5. Bang your head as hard as you can as many times as you can against this concrete wall while thrusting the big barb wired wooden stick as hard as you can up your posterior.
It will be fun compared to watching this turd of a "movie".
