Back to the Future screenwriter Bob Gale weighed in on a Twitter debate over whether the film qualifies as "perfect" by declaring a long-argued plot point is no problem.

On the question of why Marty McFly's parents don't remember him as the matchmaker who brought them together, Guardians of the Galaxy star Chris Pratt mused that they know him as "Calvin Klein," the name Lorraine learned when she brought an unconscious Marty into her home in 1955. "When Marty returns to present day 1985, it could have been years since his parents would have perhaps originally noted the uncanny resemblance between their son and that kid from high school 20 years previous," he said.

Gale agreed, telling THR, "Bear in mind that George and Lorraine only knew Marty/Calvin for eight days when they were 17, and they did not even see him every one of those eight days. So, many years later, they still might remember that interesting kid who got them together on their first date."

"But I would ask anyone to think back on their own high school days and ask themselves how well they remember a kid who might have been at their school for even a semester," Gale continued. "Or someone you went out with just one time. If you had no photo reference, after 25 years, you'd probably have just a hazy recollection."

Gale further figured that George and Lorraine wouldn't have a strong memory of a classmate they haven't seen in two decades. If they thought of him at all, they might think their son's resemblance to Calvin "wouldn't be a big deal."
