Connor Cruise, 14, will join Watchmen star Jeffrey Dean Morgan in Red Dawn.
The original 1984 movie, directed by John Milius, starred Swayze, his future Dirty Dancing partner Jennifer Grey, Charlie Sheen and C. Thomas Howell.
Reports suggest young Cruise has signed on to play Daryl, the role Darren Dalton played in the first film.
Meanwhile, producers of TV series revamp Melrose Place have confirmed Cruise will not be a part of their cast.
A representative for the show says, "There’s no truth to it."
