Michael passes on a favor from Mr. Ammer, to which Mr. Ammer replies, "I'll put Swardson on it." Nick Swardson is a friend of Adam Sandler, appearing on Sandler's most recent comedy album "Shh... Don't Tell" (2004). Swardson is also the Bed, Bath & Beyond Guy who asks Michael to be his friend.
In the "first kiss flashback," Jennifer Coolidge's character is seen wearing a shirt of The Simpsons. Julie Kavner, who played Trudy Newman/Michael's mom in this film, provides the voice for Marge Simpson on The Simpsons (1989).
In the DVD Audio commentary, director Frank Coraci states that the scene set in the past where Adam Sandler and Kate Beckinsale's characters kiss for the first time was deliberately over light to look like a late 80s/early 90s film.
Several future world events are mentioned by radio in the film as Michael fastforwards through his life. Two of these include Michael Jackson becoming the first human being to clone himself and Britney Spears having her twenty-third baby; the dates the film is set in the future span from 2017 to 2030.
The film's premise was originated from a joke by writer Steve Koren. It was not until co-writer Mark O'Keefe's girlfriend's suggestion of turning it into a feature that the project got started off the ground.
When Michael visits Ben's office, the water that Ben gives Michael is VOSS sparkling artesian water from Norway. Yet another reference to his other movies. Voss is the brand of water Sandler's spoiled kids drank in Grown Ups (2010).
The plot is similar to an episode of R.L. Stine's Goosebumps (1995-1998) season 3, episode 5 titled "Click", in which a child orders a remote that controls not just the tv, but the world around him. Not unlike Sandler's version of the story, the remote proves to be addictive and have dire consequences.
The trivia items below may give away important plot points.
Adam Sandler and this film's producers were almost sued for plagiarism by Scholastic, Inc. when its plot was revealed and all too familiar. In 1995, eleven years prior to this film, the popular author R.L. Stine wrote a very similar story in his "Tales To Give You Goosebumps," with almost the exact same plot and set-up as this film, even down to both being titled "Click." No legal action was ever taken as both agreed to the entire situation being a coincidence. The irony is that both Click (2006) and Stine's story can easily be based on the old French tale "The Magic Thread," where a boy is able to pull a thread to speed up the parts of his life he does not like and quickly finds himself an old man before being given a second chance.
