"Twin Peaks" (1990-1991) television show featured the "show within a show" entitled "Invitation to Love," a soap opera watched by characters that often mirrored events on the TV show itself. ITL featured identical twins Jade and Emerald Lancaster, (played by Erika Anderson,) one good (Jade) and the other evil (Emerald). The twins were thought by some critics to mirror the cousins Laura Palmer (evil) and Maddie Ferguson (good) although the two actual characters were not twins but closely-resembled cousins.
