I like him most in 'Marty' (1955), 'The Dirty Dozen' (1967) and especially his appearance as Ceasar in 'Gattaca' (1997)
Borgnine spent 10 years in the Navy prior to acting
he was married to Rhoda Kemins (1948 - 1959, divorced), Ethel Merman (1964 - marriage only lasted 32 days, divorced), Katy Jurado (1959 - 1963, divorced), Donna Rencourt (1965 - 1972, divorced) and lives now in his fifth marriage with Tova Traesnaes (married since 1972)
