In 1988, Chandler was signed by the American Broadcasting Company and brought to Hollywood as part of ABC's new talent program. He made his television film debut that same year as a supporting hero actor in Quiet Victory: The Charlie Wedemeyer Story. Also in 1988, Chandler studied with acting teacher, Milton Katselas. His first major acting experience was a supporting role on television as Army Private William Griner in Tour of Duty. In eight episodes of the last season of the series, he played a member of a special operations squad fighting in Vietnam.
Chandler made his film debut in one of the key roles in the 1992 George Strait film, Pure Country. From 1991 to 1993, he had a series regular role as Cleveland Indians right fielder Jeff Metcalf in the ABC series Homefront, a drama set in the post-World War II era in the fictional town of River Run, Ohio. Homefront ran for two seasons, with Chandler appearing in all 42 episodes.
In 1994, he made his Broadway debut, co-starring with Ashley Judd, in a revival of William Inge's Picnic at the Roundabout Theatre Company. From 1996 to 2000, Chandler starred as the lead character in the CBS series Early Edition, as a man who had the ability to change future disasters. He portrayed bar owner Gary Hobson, a stockbroker turned hero who received "tomorrow's newspaper today", delivered to his door by a mysterious cat. In 1996, he received the Saturn Award for Best Actor on Television for his portrayal of Hobson. Chandler was featured in all 90 episodes of the series, which ran for four seasons.

Working again in film, Chandler played the 1930s film star Bruce Baxter in the 2005 film King Kong (the character was based on romantic film star Bruce Cabot, who played Jack Driscoll in the original King Kong). Coincidentally, Chandler later played John Driscoll in The Day the Earth Stood Still.
In February 2006, Chandler returned to television to guest star as the ill-fated bomb squad leader Dylan Young in two episodes of the ABC series Grey's Anatomy.
