BBC has done a beautiful documentary about the important events of Buddha’s life, interspersed with some interviews. There is a good quote of Buddha at the description of the film:
Do not believe in something because you are told to.
Do not believe in something because a holy person said it.
Do not believe in something because you read it from a book.
Follow and practice the teaching without prejudice.
If it brings happiness to you and others and does not
encourage self harm or harm to others then follow it.
