He was born Caterino Bertaglia in Corbola, Italy on February 18th 1927. In an interview Rik says he never met his father, rarely saw his mother and was raised by his grandmother.
After having worked a few years as a seaman, legend has it that he was discovered working as a bartender, but, depending which source you choose to believe, the discovery could have been made by director Mario Soldati, producer Carlo Ponti or writer Goffredo Parise, while Rik himself said it was a talent scout. Regardless of who it was who found him, with looks reminiscent of a young Elvis Presley he was cast in the leading role opposite Italy's hottest starlet of the time, Sophia Loren, in La donna del fiume (1954). He followed up on this with a number of other leading roles over the next few years, while in 1955 he also enrolled to study acting at Centro Sperimentale di Cinematografia, putting him in the rather unique position of being an established leading man before and during his studies.
Following his graduation he relinquished his leading man status in favour of playing large supporting character roles, more often than not playing the part of the villain. With genuine acting talent beyond his matinee idol looks, Rik continued to work steadily for the next 40 years, appearing in all the popular genres of Italian cinema. From the 70's onwards his roles tended to be smaller, but he continued working regularly until retiring in 1999. From around 1977 onwards he always used the spelling "Rick".
He died of heart failure on March 27th 2015 in Corbola, aged 88.
Perhaps his best remembered roles today are from the series of Karl May westerns he appeared in during the mid-60’s, shot in Germany and Yugoslavia. He acquired something of a reputation for being romantically involved with the actresses in his films, which he confirms in an interview from 2014.
