Great Role: Sharon Mitchell
I believe a challenging role for Rachel would be to portray Sharon Mitchell, the American adult film actress who against all odds actually amounted to something after toiling in XXX movies for years.
Rachel doesn't "look like" Mitchell any more than she looks like all the actresses mentioned on these boards (Juliette Lewis, Juliette Binoche, etc.), but with her flawless American accent and ability to transform her appearance I think she could pull off this difficult assignment. There haven't been many serious attempts to deal with the porn industry other than BOOGIE NIGHTS and the Val Kilmer picture, but a talented scriptwriter could easily fashion a Mitchell biopic that also commented on the dangers & shortcomings of this segment of the entertainment business.
