Standard Blu-ray players are capable of playing 3-D movies. However, 3-D movies played on a standard Blu-ray player will not appear in 3-D.
A 3-D player is necessary to watch 3-D movies. This means many people who own traditional Blu-ray players will need to upgrade before being able to watch this type of movie.
If a user finds his Blu-ray player is not 3-D compatible and he chooses not to upgrade to a new player, he may find using a PS3 to play 3-D movies works well. In 2010, the Sony Corporation released an update giving the PS3 the ability to be able to play 3-D movies and games.
