The CW has changed the title of this week's episode from "Back to the Future II" to "The Song Remains the Same." But the premise of this unique installment remains the same:
Anna travels back to 1977 with a Terminator-esque mission in mind: she wants to kill Sam's parents before they give birth to him.
In a recent interview, Julie McNiven (Anna) previewed the special episode. Read what she had to say about it now and check out the official CW promo below:
