ESPN Films is set to air a documentary of one of the more interesting off-the-field stories of a major star in the history of SEC football.

Titled, “The All-American Cuban Comet,” the film will focus on Florida’s all-time receiving yards leader, Carlos Alvarez, and premiere tonight on the SEC Network on at 8:30 p.m. ET.

A Florida, Alvarez earned All-American honors as a sophomore wide receiver in 1969 as he and quarterback John Reaves helped the Gators to a 9-1-1 season, capped by a Gator Bowl victory over Tennessee. In three seasons, Alvarez totaled 172 catches for 2,563 yards and 19 touchdowns.

Alvarez is also remembered for participating in anti-Vietnam War protests, actively supported the integration of Florida’s football team and was a founding member of one of the country’s first student-athlete unions. In 2011, Alvarez became the first foreign-born Hispanic-American to be inducted into the College Football Hall of Fame.

“One of the things that was most exciting to us about Carlos’s story was that the fights he waged 50 years ago are completely relevant to the current moment,” filmmaker Gaspar González said. “Carlos understood the connection between civil rights and athletes’ rights. If you think of that generation of the 1960s, the athletes who fused sports with social consciousness, Carlos Alvarez is right there. He deserves to be remembered for that, in addition to being one of the great receivers in college football history.”
