Hamilton's acting debut came first with guest starring appearances on television. Hamilton's film debut was a lead role in the
horror film Children of the Corn. The movie was panned by critics, but it made a profit at the
box office, and had a strong
cult following. Hamilton's next role was in
The Terminator in 1984. The movie was a huge commercial success. Following
The Terminator, Hamilton starred in
Black Moon Rising, an action thriller starring
Tommy Lee Jones. She then returned to television in the mystery comedy
Murder, She Wrote, scoring favorable reviews.
Hamilton then starred opposite
Ron Perlman in the TV series
Beauty and the Beast. The series was critically-acclaimed and she received
Emmy and
Golden Globe nominations. Hamilton left the series in 1989; after the series ended in
1990, Hamilton went back to the big screen with the follow-up to
The Terminator,
Terminator 2: Judgment Day. The film was a smash at the box office, grossing over 500 million, and becoming the highest grossing film of
1991. Her identical twin sister
Leslie Hamilton Gearren was Linda's double in
Terminator 2: Judgment Day. Hamilton reprised her
Terminator 2 character,
Sarah Connor, for the theme park attraction "T2-3D".
Due to the success of the
Terminator series, Hamilton hosted
Saturday Night Live. She then returned to television in
A Mother's Prayer playing a mother who lost her husband and is diagnosed with
AIDS. She earned yet another
Golden Globe nomination. That same year, Hamilton filmed two motion pictures,
Shadow Conspiracy and
Dante's Peak.
Shadow Conspiracy flopped at the box office, but
Dante's Peak opened in at number two with an opening gross of 18 million, going on to gross 180 million. Hamilton has since appeared on
Frasier and has done more TV movies, including
On the Line,
Robots Rising,
Rescuers: Stories of Courage: Two Couples,
Point Last Seen, and
The Color of Courage.
