Adam and Eddy have confirmed in an interview that “Back to the Future” is one of their favorite screenplays ever. I think that this is confirmation that the plot for 3×21 was directly inspired by that film series.
Access: Emma and Hook go back in time in the Enchanted Forest this week, and I know you guys are ‘80s fans, so you’ve probably watched every ‘Back to the Future’ movie. We know Marty McFly had trouble when he disrupted the space-time continuum.
Eddy: Did he!Access: So tell me, what kind of troubles are Emma and Hook are going to run into?
Adam: Well first, on that front, if we haven’t already said it, Episode 19’s title, ‘A Curious Thing,’ was our homage to the Huey Lewis ‘Power of Love’ song.
Eddy: From ‘Back to the Future.’ … For me and Adam, one of our favorite scripts ever and the one we wished we wrote was ‘Back to the Future.’
Adam: Yeah, it’s an amazing screenplay.
Eddy: I would say that this week, as you just said, time travel is tricky business and the littlest thing can have the biggest consequences, so we hope our heroes…. don’t touch anything.
Adam: And don’t do any sports betting.
