Harrison Ford's son thinks his marriage is "wonderful".

Chef Ben Ford - whose mother is the 'Indiana Jones' star's first wife Mary Marquardt - is delighted the actor finally tied the knot with his long-term girlfriend Calista Flockhart on Tuesday (15.06.10).

Ben told People magazine: "Those crazy kids went off and eloped I think it is wonderful that they finally made it legit. It is really terrific news. I'm so happy for them."

Harrison, 67, and the 45-year-old actress wed at the Santa Fe mansion of New Mexico's state governor Bill Richardson - who presided over the ceremony with the assistance of the state's Chief Justice, Charles W. Daniels - following a 16-month engagement.

Governor Richardson and his wife were witnesses for the couple, and the former 'Ally Mcbeal' actress' nine-year-old adopted son Liam also attended the ceremony in the southern state - where Harrison is filming 'Cowboys and Aliens' with Daniel Craig.

Harrison and Calista began dating after they met at the 2002 Golden Globe Awards ceremony.

The 'Indiana Jones' actor has been married twice before, with his divorce to second wife Melissa Mathison concluding in 2004.
