(You need to Login or Register to view media files and links)If this were filmed in early 1997, using actors from that very same period of time, it would definitely include:
David Gallagher (Jack)
Michael Angarano (Ralph)
Keegan McIntosh (Simon)
Miko Hughes
Mason Gamble
Eric Lloyd
Joseph Cross
Eli Marienthal
Brawley Nolte
Joel Palmer
Andrew Ducote
Tom Felton
Paul Terry
Justin Berfield
William Greenblatt
T.J. Lowther
Using the 'time-travel' option, David Gallagher would still play the role of Jack.... but Ralph would be Clay O'Brien, and Simon would be a toss-up between Sonny Bupp and Shane Sinutko, (giving them both at least a dozen screen-tests to 'win' the part.)
Ricky Schroder from 1980 would play the role of both twins, utilizing the best methods in doubling his character on screen.
In the rest of the cast, David Ladd, Gary Gray, Scotty Leavenworth, Fergus McLelland, Ricky Sorenson, Philip De Lacy, Keegan McIntosh, Dickie Moore, Barret Oliver, Badget Dale (yes he returns), Johnny Sheffield, William Dix, and Billy Lee.
