Cal Thomas was born in Santo Domingo, Dominican Republic, and left his homeland at the tender age of nine to attend various boarding schools in the United States, with his journey taking him to Florida, Connecticut, and California before attending college in Massachusetts and subsequently moving to New York to pursue his acting career.
Following his arrival in Los Angeles in 2002, Cal began to hone his writing skills, with his first screenplay, "Rubi", leading to a collaborative effort with producers Sergio Aguero and Lynnette Ramirez on the romantic comedy "Lover's Block". This initial success was followed by his being hired to adapt the French film "Dis-moi oui" for the American market. In 2003, Cal went on to form Red Jacket Productions, with his first project as a producer being the title "The Last Race", which resurrected the poignant love story between James Dean and Pier Angeli. This project, which caught the attention of then-Paramount Chief Sherry Lansing, led to Cal's consideration for the role of Prince Edvard in "The Prince and Me".
In 2004, Cal accepted a role in the film "Afterthought", where he played the part of Elliott Smithe, a Columbine-type serial killer. This performance led to an offer from Kalpana Singh-Chitnis for a role in "Adios, Mi Amigo", an epic story of American immigration, in which Cal plays Jose, a Mexican immigrant who crosses the border illegally with his son and best friend in the early 1970s. Additionally, his role in "Afterthought" also led to a cameo as an undercover police officer in the urban drama "Patrol", which was completed in 2006. That same year, Cal wrote "Penance", a thriller about a serial killer who gets his victims to kill themselves as a penance for their own sins.
In 2007, Cal relocated to the Principality of Monaco, where he splits his time between Los Angeles and Monaco.
