We found this article about Lost’s actor and this is the part about Liz:
Elizabeth Mitchell (Dr. Juliet Burke)
Elizabeth Mitchell followed up her time on Lost with two short-lived series that couldn’t help but share its DNA: the modern remake of Eighties hit V, along with the shameless Lost knock-off Revolution. She’s also something of a TV movie regular, appearing in sensationalist true-crime story Prosecuting Casey Anthony, and holiday movie Kristin’s Christmas Past. 2016 saw her pop up in The Purge: Election Year and the horror series Dead of Summer.
