Pepito played a large role in the pilot for the “I Love Lucy” show.  Five months pregnant, Lucy stepped before the live TV cameras at Studio A at CBS headquarters on Sunset Boulevard and Gower Street on March 2, 1951, to do the "audition film." A 16mm print of the proceedings (known as a kinescope) was made to show to advertising agencies in New York in hopes of finding a sponsor willing to underwrite the cost of producing "I Love Lucy." (At the last minute, Lucy and Desi's character names were changed from Lucy and Larry Lopez to Lucy and Ricky Ricardo when somebody pointed out that there could be some confusion over real-life orchestra leader Vincent Lopez.)
