Behind-the-scenes information

Marty as Calvin comes face-to-face with his teenage mother Lorraine.

" Marty suddenly became aware of his pants folded across the chair in the opposite corner [of the bedroom]. Reaching down beneath the covers, he realized he was clad only in his underwear. / "We took your pants and shirt off when we put you in bed," Lorraine explained. "I've never seen purple underwear before, much less purple underwear with a man's name written on it." / "Oh," Marty replied. "That isn't my name. Calvin Klein is the name of the underwear manufacturer." / "And your name's Marty?" she asked. / "Yes." / "Well, I'm pleased to meet you, Marty," she said, sitting on the bed. Her attitude seemed different now, much less motherly, more seductive. / "And what's your last name?" she smiled. "
—From Back to the Future by George Gipe (quote, pages 101 and 102)

Alias of Marty McFly[]

For a full biography, see the article on Marty McFly.

The "Calvin Klein" alias was taken by Marty McFly in 1955, after Lorraine Baines noticed the name on his purple underwear.

She assumed it to be Marty's name. Marty did not correct her that it was actually the manufacturer's name (possibly figuring that she would find it suspicious, as the real Calvin Klein company would not exist until 1968), only told her that most people call him Marty.

Lorraine continued referring to him as Calvin, and the rest of the people Marty met in 1955, such as Biff Tannen, did as well. When Lorraine followed Marty to Dr. Emmett Brown's mansion, he told her that Doc was his uncle.

In 1958, Lorraine was fighting with George McFly, due to the fact that his newfound confidence made him arrogant, and she considered breaking their engagement off. Lorraine came to Doc's mansion looking for "Calvin". Doc told her that he was away at college, but knowing that they had to stay together in order for Marty to be born, Doc came up with a plan to tell George what to say to Lorraine using a tiny radio receiver that he invented based on Marty's walkman, akin to Cyrano de Bergerac. However, George thought Lorraine was cheating on him with Doc, and stormed in on them, accidentally setting off Doc's Static-O-Matic electric hair chair. They both had a laugh at his frizzled hair caused by the static, and George realized that he didn't have to be so uptight all the time. Doc realized that arguments are usual in relationships, and he was able to rest easy knowing that they would stay together.

In 1986, Marty McFly and Professor Marcus Irving borrowed Doc's second DeLorean time machine to travel to 1972. They intended to discover why Marty's uncle Joey went to prison. Prof Irving told Marty that his teenage self was known by the residents of Hill Valley and told him to stay out of sight, reminding him that 1972 was not that far from 1955.
