Appearing in many guest roles over the years he once again found fairly steady work. Then as luck would have it in 1966 the iconic television series Batman that stared Adam West and Burt Ward was launched. Neil Hamilton, then 67 was cast as the stoic Commissioner Gordon and appeared in all 120 episodes.
Here is a photo dated 1945 showing Neil Hamilton visiting Falcon Lair and looking at a coat that Valentino wore in "The Eagle" he is standing in the living room and you can see the fireplace to his right. This was during the time when Juan Romero was liquidating the Valentino owned items he had. Apparently he was trying to obtain press coverage by having actor Neil Hamilton photographed at Falcon Lair with Rudy owned items.
