Following a week of rehearsals, Lohan is now all set to portray late movie icon Elizabeth Taylor in the biopic.
Executive producer Larry Thompson tells PerezHilton.com, "This is really happening... She is number one on the call sheet. She is the star."
And Thompson can't wait for film fans to see his leading lady as Taylor after the top-secret TV movie is shot.
He adds, "When you see both of them (Lindsay and co-star Grant Bowler) in full hair and make-up, it is the definition of movie magic."
Bowler is playing the love of Taylor's life, Richard Burton, in the film.
