During the filming of The Wild Wild West episode "The Night of the Juggernaut," Ross Martin broke his leg. For the show, he was only filmed from the waist up to hide the injury.
Ross Martin was an accomplished musician, showing virtuoso talent with the violin as early as age eight. He would continue to play and perform throughout his life.
Ross Martin: (describing his ad-libs on the set of "The Wild Wild West") I've been allowed to add a bit of dialogue to the characters now and then, just to help the illusion. When I portrayed a German count, there was a scene where a tough dived at me from the stairway. I side-stepped him and ad-libbed, "Have a nice trip." I was allowed to keep it in. Later, one man grabbed me from behind and another came at me from the front. I added, "That's no way to treat an old man." That was left in too.
Ross Martin: (describing the challenges with appearing in costume) I went home one afternoon to pick up a script without bothering to change, and a half an hour later the Beverly Hills Police were at my door because a neighbor had reported a suspicious stranger lurking around Ross Martin's house. I had to peel off my beard to prove who I was.
