Chris Martin for a flashback Driveshaft reunion where he joins the fictional band cuz Charlie died and they get the O6 on their tourbus and totally drive them to the harbor/airport or whatever!!! lol it's stupid but meh CHRIS MARTIN? lol And he's a big Lost fan I heard he made a song inspired by Lost on his latest album.
Ian McKellen (if they need some Uber Sci Fi presence for once or twice he would fit the bill but for a series regular id rather have Patrick Stewart
Christopher Eccleston (tell me he couldnt make an awesome Widmore Thug or maybe Dharma guy we havent seen before)
Blake Lively (if a hot chick is needed and shes FRESH)
Nathon Fillion (from Firefly, geek cred and needs a job badly, people would spooge)
