From 1956 to 1972 how many commercially released films did Elvis Presley appear in?

Elvis Aaron Presley (January 8, 1935 – August 16, 1977) was an American singer and actor. Regarded as one of the most significant cultural icons of the 20th century, he is often referred to as the "King of Rock and Roll" or simply "the King".

From the moment he burst onto the music scene in the 1950s, to the late Vegas years of garish jumpsuits, Presley’s career tells a host of intriguing tales. From an economics point of view, however, his roster of entirely forgettable, but wildly successful movies offers the most fertile ground.

Many people are familiar with the existence of Elvis’s films, even if the plotlines don’t spring immediately to mind. Between 1956 and 1972, he made 33 movies, and in all but one he took the starring role. And they were popular. In today’s money, the total box office receipts equate to over US$2.2 billion, and that is for the US alone.
