He is famous for his films among many other things.
We use among when someone or something is part of a group: ‘Who among all those people is your brother?’
We use between for separate people or things. It can be used with two or more: ‘The negotiations between the club, the fans and the government are going well.’ ‘Let’s keep this secret between you and me.’
We also use the fixed expression among other things, not between other things.
