"Airport 1975" released 1974

I suppose the success of Airport in 1970 was the main impetus behind the making of this movie, to which the only connection to Airport 1975 is George Kennedy as Joe Patroni.  Airport 1975, released October 18, 1974, was a box office blockbuster, becoming the third largest grossing film of 1974 behind The Towering Inferno and Earthquake, which starred both George Kennedy and Charlton Heston (Alan Murdock in Airport 1975).

Critics were not impressed, and the movie has been inducted into the Razzie Awards' Hall of Shame (along with its two sequels).

Dana Andrews plays Scott Freeman, the pilot of a twin-engine private Beechcraft Baron, who has a heart attack in flight and crashes into the cockpit of a 747, killing two crew members and blinding the captain.  Airport 1975 was heavily parodied in Airplane!, a comedy taken from Zero Hour! which also starred Dana Andrews.

The cast was star-studded with big names like Gloria Swanson, Karen Black, Efram Zimbalist, Jr., Susan Clark, Linda Blair, and Helen Reddy.

Reddy garnered the only award nomination as she was nominated for the Golden Globe for Most Promising Newcomer - Female.

"The Ten Commandments" debuts 1956

Cecil B. DeMille's epic movie The Ten Commandments, was released into theaters October 5, 1956. The film followed the life of Moses and his journey with God, freeing the Israelites from Egypt, and delivering the Ten Commandments to the people.

Charlton Heston played Moses and Yul Brynner starred as the pharaoh Rameses.  It featured many other big names such as Yvonne De Carlo, Judith Anderson, and Vincent Price.

It won an Academy Award for Best Special Effects and nominated for six more, including Best Picture. Charlton Heston was nominated for a Golden Globe for his performance as Moses.

The Ten Commandments was added to the National Film Registry by the US Library of Congress in 1999.

"Earthquake" released 1974

Universal Pictures released its blockbuster disaster movie Earthquake November 15, 1974.  After the success of Airport (1970) and The Poseidon Adventure (1972), a slew of disaster pics were released in 1974 including The Towering Inferno and Airport 1975.  Earthquake was the third grossing film of the year, with The Towering Inferno being the top-selling film.

The movie has an all-star cast that includes Charlton Heston, George Kennedy, Victoria Principal, Ava Gardner and Lorne Greene.  It won an Academy Award for Best Sound and one for Special Achievements in Visual Effects.

"Planet of the Apes" released 1968

Planet of the Apes, a science fiction classic, was released April 3, 1968.  It was based on the novel by Pierre Boulle (Bridge Over the River Kwai).  It starred Charlton Heston, Roddy McDowall and Kim Hunter. 

It involves a crew of astronauts who crash land on Earth in the distant future, where apes have evolved and are the dominant species.  Humans are kept as slaves.

It was nominated for two Academy Awards and won an honorary Oscar for John Chambers' achievements in make-up.  This didn't become a category until 1981.
