Robert Jackson "R.J." Williams (born 19 July 1978; age 36) is the actor who portrayed Ian Troi in the second season episode of Star Trek: The Next Generation called "The Child". Archive footage of his appearance was also used in the episode "Shades of Gray" later in the season.
Williams has made a name for himself in television, earning several Young Artist Award nominations for his work on various series. He is best recognized by soap opera fans for playing Rowdy on General Hospital from 1989 through 1991. TV audiences may also remember him for playing young Thomas Magnum on Magnum, P.I. and Ricky on Full House. Among the other TV series he has appeared on were T.J. Hooker, starring William Shatner, James Darren, and Richard Herd, and St. Elsewhere, starring Chad Allen, Ed Begley, Jr., Norman Lloyd, Deborah May, France Nuyen, Alfre Woodard, and Jane Wyatt.
In addition, Williams has lent his voice to a number of youthful cartoon characters, including the title character of Dink, the Little Dinosaur, Kit Cloudkicker on Disney's TaleSpin (which also featured the voices of Janna Michaels, Tony Jay and Frank Welker), and Cavin on Disney's Adventures of the Gummi Bears. (He replaced fellow Trek performer Jason Marsden in the latter role for the show's last season.) Williams was also the star of the popular family series Wake, Rattle & Role from 1990 through 1992.
One of Williams' earliest television appearances was in the TV movie The Other Woman, which also featured Star Trek: Voyager star Robert Picardo in the cast, as well as Gregory Itzin. He later appeared in a few more made-for-TV movies, as well as a number of feature films, including American Anthem (1986, with Michael Pataki and Googy Gress), The Price of Life (1987, with Roy Brocksmith and John Fleck), and A Man of Passion (1989, with Ray Walston).
Now known as "The Ultimate Insider" for his reporting on the entertainment industry and Hollywood happenings, Williams recently hosted and produced the one-hour VIP Access TV specials. He also hosted and executive produced the 2005 and 2006 Young Hollywood Awards ceremonies.
