Child actor
Child actor Craig Hundley, who played Tommy, would go on to become a composer and inventor under the name Craig Huxley. His Blaster Beam, an 18-foot (5.5 m) long aluminum bar strung with piano wire and played using artillery shells, would appear on Jerry Goldsmith's soundtrack for the first "Star Trek" film, as well as James Horner's "Star Trek II" and "Star Trek III" soundtracks. Huxley also composed the piece "Genesis Project" for the "Project Genesis" briefing video in "Star Trek II".
