Pnau, who have claimed this year's ARIA award for Best Dance Release, say they are working on a movie soundtrack with Elton.
They spoke to reporters at the Sydney awards ceremony.
''We're doing a movie right now. We're not allowed to say what it is, but we're doing some stuff,'' bandmember Nick Littlemore said on Tuesday night.
He said that the pop veteran has been a good friend of the group since reaching out to them, after being impressed by their 2007 self-titled album.
''He's been a lovely and supportive person over the years,'' Nick added.
