Trivia: While still of high-school age, Marjorie Lord was a contract ingenue at RKO, playing the deadpan leading lady in two Wheeler and Woolsey comedies: Off Again On Again (1937) and High Flyers (1937). She moved to Universal Pictures in the 1940s, where she was decorative (and little else) in the studio's serials, westerns, and "B" pictures (notably 1942's Sherlock Holmes in Washington). Her best role during this period was opposite James Cagney in Johnny Come Lately (1943); she later had the chance to essay a villainous characterization in the independently produced The Strange Mrs. Crane (1948). Full stardom eluded Lord until 1957, when she replaced Jean Hagen as Mrs. Danny Williams on TV's The Danny Thomas Show (aka Make Room for Daddy). She played Kathy Williams until the series' cancellation in 1964, then re-created the role in the 1969 "revival" series Make Room For Granddaddy. She continued acting until the mid-1980s. The mother of actress Anne Archer, with whom she appeared in the 1978 TV movie Harold Robbins' The Pirate., Lord died in 2015, at age 97.

Trivia: Though she was best known as a young TV star, Angela Cartwright also appeared in perennial movie musical favorite The Sound of Music (1965). Born in England, Cartwright's family moved to Los Angeles when she was three. Cartwright soon made her film debut, at the ripe old age of three and a half, in Somebody Up There Likes Me (1956). Cast in 1957 as stepdaughter Linda on Danny Thomas' TV hit Make Room for Daddy, retitled The Danny Thomas Show, Cartwright stayed with the series until it ended in 1964. It was Cartwright's two mid-'60s credits, though, that captured the most devoted fans. As The Sound of Music's pretty Brigitta Von Trapp, Cartwright became one of the seven children taught to sing and love life by buoyant nun/stepmother Julie Andrews. With its Rodgers & Hammerstein songs and unbridled sentiment, The Sound of Music broke box office records, becoming a beloved classic. Cartwright then joined the cast of Irwin Allen's low-tech TV series Lost in Space as young teen daughter Penny Robinson. Though the show only ran from 1965 to 1968, Lost in Space attracted a durable cult following; Cartwright had a cameo in the 1998 film version. After Lost in Space ended, Cartwright made sporadic appearances in films and TV in the subsequent decades, including Irwin Allen's disaster flick sequel Beyond the Poseidon Adventure (1979). Married since 1976, Cartwright has two children and made a career outside of acting as a photographer, writer, and boutique owner. Her older sister is actress Veronica Cartwright.

Trivia: The son of legendary vaudevillian Pat Harrington Sr., comic actor Pat Harrington Jr. rose to prominence via his many appearances on The Steve Allen Show and The Jack Paar Program in the late 1950s. However, few viewers recognized him as Pat Harrington Jr.: instead, he passed himself off as Italian golf pro Guido Panzini, a guise so convincing that he was invited to play in several major tournaments. Once the public at large was apprised that Harrington was neither Italian nor a master duffer, demands for his services as an actor increased immeasurably. In 1959, he was cast on The Danny Thomas Show as Danny's new son-in-law Pat Hannigan (Thomas had planned to spin off Harrington and his TV daughter Penney Parker into their own series, but this was not to be). In 1962, he served as host of Stump the Stars, a revamped version of the old Summer replacement perennial Pantomime Quiz. Seven years later, he was seen as sharkish PR man Tony Lawrence on the short-lived TV adaptation of Mr. Deeds Goes to Town. In 1975, Harrington landed his signature role as macho, aphorism-spouting handyman Dwayne Schneider on the TV sitcom One Day at a Time; he remained with the series until its cancellation in 1984, earning an Emmy along the way. In films, Pat Harrington Jr. has been seen in a gallery of diverse portrayals, most amusingly as smoothly villainous telephone company spokesman Arlington Haven in The President's Analyst (1967). Harrington continued to act until 2012; his last acting appearance was a guest-spot on Hot in Cleveland, starring his former One Day at a Time co-star Valerie Harper. He died in 2016, at age 86.
