Word came out over the weekend that Jake Scott, director of 'Welcome to the Rileys,' will be helming a big screen biography of late rocker Jeff Buckley.

Performing as a session musician before releasing his seminal and beloved album, "Grace," in 1994, Buckley drowned in the Wolf River in Tennessee before he could complete work on his second record.

Buckley boasted an ethereal voice and impressive guitar skills, and, though he passed at age 30 and released only one proper album, influenced a generation of musicians. It will be a much sought after role -- the question is, who should play it?

The license to use Buckley's music was part of the deal, so a good singer may not be necessary. But should the star be able to sing? Or is the look and attitude more important? Here are some casting possibilities.
