He began working in cinema industry at a young age thanks to his father. According to an interview, his first appearances date back to the late 1950s, during the golden age of peplum.
But his career was primarily linked to the Italian Western genre, and his contribution to these type of movies was notable. His first appearances in westerns date back to the mid-1960s in minor stunt roles. Toward the end of the 1960s, he began to land increasingly important roles, becoming one of the most iconic faces of Spaghetti Westerns over the following decade.
In his early years, he appeared with a well-groomed mustache and sometimes even a goatee. Later, he began to grow a full, unkempt beard, his most iconic look.
Remo died on February 14, 2014 in Rome in his house in the “Quarticciolo” district, at the age of 86.
