Apart from occasional voiceover works, this is Rick Moranis' first theatrical acting role since 1997, when he appeared in Honey, We Shrunk Ourselves! (1997).
This movie is a continuation of the original movie, while ignoring the previous installations.
Directed by the original director of "Honey I Shrunk the Kids".
As this will ignore the events of Honey I Blew Up the Kid (1992) and Honey We Shrunk Ourselves (1997), the character of Diane Szalinski Wayne's wife will not be in this sequel. Marcia Strassman who portrayed Diane in the first two films died in 2014, and Eve Gordon who replaced Strassman in Honey We Shrunk Ourselves was not asked to come back again as Diane so Diane has been written out of the script as having passed away leaving Wayne (Rick Moranis) widowed.
Rick Moranis's first theatrical film since Brother Bear (2003).
