John Brown

Braun bir nechta mashhur radioshoularda bosh rollarni ijro etgan: u Fred Allenning "Allen's Alley" dasturining "Texaco Star Theater" talqinida "Jon Dou", "My Friend Irma" shousida Irmaning sevgilisi Al, shuningdek, "The Life of Riley" dasturida ham "Gillis", ham Digby "Digger" O'Dell rollarini o‘ynagan (bu rolni u teleserialning birinchi talqinida ham ijro etgan), "The Damon Runyon Theatre"da "Broadway" hamda "The Adventures of Ozzie and Harriet" radioshousida qo‘shni "Torni" obrazlarini gavdalantirgan. Uning eng esda qolarli ishi shubhasiz "Broadway" roli bo‘lgan; uni eshitganlar Damon Runyon hikoyalari sharhlovchisini boshqa aktyor tasavvur qilishi qiyin. Bu ingliz millatiga mansub aktyorning chinakamiga amerikalik xarakterni mukammal gavdalantirgan iste'dodidan dalolat beradi. Braun shuningdek, ayrim mashhur filmlarda ham suratga tushgan: Alfred Hitchcockning "Strangers on a Train" (1951) filmida mast professor rolini o‘ynagan, shuningdek, "The Day the Earth Stood Still" (1951, titrlarda ko‘rsatilmagan) va "The Wild One" (1953) filmlarida qatnashgan. U 1953-yilgi kult ilmiy-fantastik "Robot Monster" B-kino filmida "Ro-Man" ovozini bergan.
