战时海军服役后，艾伦·诺斯（Alan North）在纽约开始了他的演艺生涯，担任舞台经理。他首先在百老汇的“Plain and Fancy”中工作，并兼任艾萨克·米勒（Isaac Miller）的一小部分的替补。该剧在 1955 年至 1956 年间取得了成功（461 场演出），这导致了在百老汇内外的各种作品中的进一步表演工作，从音乐喜剧到直接的戏剧部分。艾伦最后一次出现在 1999 年在签名剧院的“好莱坞湖”中作为一个古朴的 curmudgeonly 角色。

After wartime naval service, Alan North began his show business career as a stage manager in New York. He first worked on Broadway in "Plain and Fancy", doubling up as understudy for the small part of Isaac Miller. The play had a successful run between 1955 and 1956 (461 performances) and this led to further acting work in diverse productions, ranging from musical comedy to straight dramatic parts, both on and off Broadway. Alan last appeared as a quaint curmudgeonly character in "Lake Hollywood" at the Signature Theater in 1999.
