That was the main giveaway for me too. Sure there are lots of technical things that give it away, but this man couldn't act to save his life. When he first reached the tree with his parachute, I couldn't help but burst out laughing at his "anger".
Oh man I skipped right over that. Terrible acting and he went for the cliche of getting stuck in a tree. If he's an experienced skydiver, surely he could have easily landed in a better spot.
