Actress Genie Francis, who played Laura but hasn't been on "General Hospital" since 2013, has returned to participate in the story of Luke's exit. They've teamed up to save their son Lucky, played by Jonathan Jackson. They believe Lucky has been kidnapped. Jackson, who left the show in 2011, will also briefly reprise his role to help usher out the character of Luke.

Geary, 68, began playing Luke in 1978. He said in a statement that he originally signed on for a 13-week stint. He said except for an eight-year hiatus in the 1980s, "Luke Spencer has been my alter ego ever since. I'd like to thank ABC, my producers and the GH audience for a long and exciting ride."

Geary has received a record eight Daytime Emmy Awards for his work as Luke Spencer.

"General Hospital" marked its 52nd anniversary in April and is the only remaining soap opera on ABC. It's the longest-running daytime drama on television.
