Well I was going to say Ryan Phillipe could play a young Lindsey, with darker hair of course, but then I remember that megamovie, huge production from few years ago. There is already a Fleetwood Mac movie, my dear ledgies, with famous actors, that 2 acamedy awards winner who played Stevie. The actor who plays Mick is a shakespearan famous british. Don't you remember it?? Don't know why but they chose Gene Wilder for the Lindsey role (or it was the Bob W. role??)
