The 26-year-old actress, who stars opposite Grant Bowler as Richard Burton, went braless in a silver gown with red-beaded keyhole cut-outs down the middle, revealing her cleavage and toned midriff.
And the star wore her trademark red hair loose over her freckled shoulders and added lashings of red lipstick to her ample pout.
Speaking about playing the late legendary actress, Lohan recently told Jay Leno on The Tonight Show how she became "good friends" with Taylor's former nurse, adding: "It was nice to kind of have the inside things that I didn't know about Elizabeth.
"When she was home in bed she would karaoke sometimes to [radio station] 103.1!"
The Elizabeth Taylor biopic, which depicts the torrid romance between Taylor and Burton, premieres in the US on Lifetime Television on November 25.
