Early life :

Cullen was born August 26, 1956, in Houston, Texas, the son of Catherine and Lucien Hugh Cullen, an oil industry executive and part of one of the most famous and wealthiest oil families in the oil-rich history of Texas. He graduated from Madison High School in Houston in 1974, subsequently attending the University of Houston from which he graduated in 1979. His alma mater awarded him a Distinguished Alumni Award in April 2012.

Cullen has given great credit to his highly acclaimed acting mentor and University of Houston professor, Cecil Pickett, who also mentored such Houston-born actors as Dennis Quaid, Randy Quaid, and Brent Spiner. Cullen and Dennis Quaid's close friendship, which continues to this day, dates back to the 1970s; it is Cullen who introduced Dennis Quaid to his former wife, Kimberly Buffington, at a dinner in Austin, Texas.
