If you can't be Batman - then be Rael
Apart from being in Thumpermonkey, which is ultimately cool in its own right, Rael is screen composer and pretty much spends his life swanking around on red carpets and conducting orchestras.
He's scored loads of stuff as diverse as My Cousin Rachel to Alpha Papa.

When he's not scoring for other people he writes his own remarkable chamber music.
He signed some copies of 2013's Mandrake for me, ahead of his new album coming out.
