Indy's bridge breaks and he is hanging by it with the natives shooting arrows at him. If you look closely you can see two arrows bounce off his back. All the other clatter noisily onto the cliff-face or stick in the bridge, so it's not like they've lost much force due to the range.
The movie opens with a scene in a night club. After the fight is over, and Indy and Willie make their escape, the name of the club is seen as they drive away - Club Obi Wan - a reference to Star Wars, also by George Lucas.
