He was the auditor in It's A Wonderful Life.
In the episode of I Love Lucy where Lucille Ball gave birth, Lane played a character he described as “this old guy who is expecting his 10th child or something”, in the waiting room with pacing, nervous father-to-be Desi Arnaz. Lane appeared on several other episodes of I Love Lucy, playing different harried or put-upon characters. On Bewitched, he made at least eight guest appearances, but never played the same character twice. On Petticoat Junction, he player the cost-cutting railroad executive who tried to eliminate Hooterville’s train service. On Dennis the Menace, he was Mr. Finch, the old man who ran the drug store. On Soap, he had a recurring role as Judge Petrillo. On The Beverly Hillbillies, he played Nancy Kulp’s untrustworthy landlord.
All told, Lane appeared in more than 150 films and hundreds of television shows. On his busiest days, Lane said he sometimes played more than one role — getting into costume and filming his two or three lines on one set, then hurrying off to another set for a different costume and a different role. Despite his stern, hardhearted demeanor in films and television, friends and acquaintances seem to unanimously describe Lane as warm, funny, and kind. He has never been arrested, never been fodder for the Hollywood press. He was a founding member of the Screen Actors Guild in 1933.
