The title of which 1963 comedy with a super cast contained the same word repeated four times in a row? b. Name any one star.

The 1963 film in question is the epic comedy "It's a Mad, Mad, Mad, Mad World." This movie was director and producer Stanley Kramer's first attempt at a comedy, a significant departure from his usual work on serious dramas like "Inherit the Wind" and "Judgment at Nuremberg (Review)." The film follows a diverse group of strangers who embark on a frantic and chaotic race across California to find $350,000 in stolen cash, after the dying thief reveals its location. The story was intended to be the ultimate comedy, leading to its grand scale and lengthy running time.

What truly made the film a spectacle was its incredible ensemble cast, which brought together a remarkable number of comedy legends from different eras of cinema. The principal cast included such luminaries as Spencer Tracy, Milton Berle, Sid Caesar, Buddy Hackett, Ethel Merman, Mickey Rooney, Phil Silvers, and Jonathan Winters. Beyond the main players, the movie is also famous for its numerous cameo appearances by other comic greats, including Buster Keaton, Jerry Lewis, The Three Stooges, and Jack Benny, making it a time capsule of mid-20th century American humor.

Filmed in the stunning Ultra Panavision 70 widescreen format, the movie was a major critical and commercial success. It was designed to be an "epic" film, a strategy Hollywood used in the 1960s to draw audiences away from television and back into movie theaters. The film's madcap energy, spectacular stunts, and the sheer star power on screen have cemented its status as a classic, influencing action comedies for decades to come.
