The Extended Edition is 130 minutes. It was released in 2007, and contains 26 minutes of previously deleted scenes, including Frances Fisher's role as Mrs. Kopecki.
UK cinema and video versions were cut by 2 secs to remove one use of the word 'fuck' for a PG certificate. The cut was restored in the 2007 12-rated Family Fun DVD edition.
Some believe that a home video release of this movie in New Zealand included an alternate ending. The alternate ending allegedly shows young Josh sitting in his classroom at school when he turns around to notice a young female classmate of whom who he recognizes as Susan- who went back to the fairground machine and wished that she was Josh's age. Some claim that this version was also seen on Latin American television. The Book of Lists, Canadian Edition, 2005 includes the following account: "During test screenings, an additional scene was included at the end, in which Josh is back at school, and a new girl named Susan arrives. The implication is that Susan used the same machine to make herself young to grow up with Josh. Due to audience feedback, this scene was cut, and so the movie ends when Josh goes back home."
The Region 4 DVD release removes the use of the 'f' word. Approx 10 seconds is altered overall.
