I'm watching Bill & Ted's Excellent Adventure (1989)

Alex Winter claimed that he gets two types of letters from teachers; positive ones from history teachers for encouraging students to learn about history, and negative ones from English teachers for affecting the way students speak.

The phone booth time machine was given away as a contest prize by Nintendo Power magazine, which was promoting Bill & Ted's Excellent Video Game Adventure (1991).

Originally, the plot was to have Bill and Ted visit, and accidentally cause, all of history's greatest tragedies, including the sinking of the Titanic and the crash of the Hindenburg.

The film takes place in 2688, May 1988, 1805, 1879, 410 BC, the 1400s, 1901, 1810, 1429, 1209, 1863 and 1,000,000 BC.

Originally, Alex Winter auditioned for the role of Ted, and Keanu Reeves auditioned for the role of Bill.

When filming began, Keanu Reeves was 22 and Alex Winter was 21, much closer to high school age than typical Hollywood productions.

Napoleon "pigs out" on a Neapolitan sundae at Ziggy Piggy's that he calls "La glacé". Despite the similarities between the ice cream and his name, the dessert originated in Naples, Italy. Historically, Napoléon Bonaparte was fond of it.

According to Alex Winter, filming in the phone booth was so unpleasant that he and Keanu Reeves nicknamed it "The Death Box."
