Oscar-winning actor Matthew McConaughey has revealed that when he started acting he thought it would be a "summer hobby". 

The 50-year-old Hollywood star first came to prominence in the 1993 coming-of-age comedy, Dazed and Confused, before starring in a string of hit romantic comedies. 

McConaughey's career evolved with more dramatic roles, leading to a best actor Academy Award win for his portrayal of a cowboy diagnosed with Aids in 2013 biopic Dallas Buyers Club.

Despite his glittering success, the Texan revealed he never set out to conquer Hollywood and believed acting would remain a hobby.

During an appearance on US TV, McConaughey discussed his late father's influence, describing how he died five days into the shoot for Dazed And Confused.

He said: "So, at that time where I took on something, acting, I thought might just be a summer hobby, I might never do it again, he was alive five days into me shooting it.

"So he was alive when I started something that I thought might be a hobby but turned into a career. So, there's a great serendipity in that for me."

McConaughey, who has three sons with wife Camila Alves, also revealed he viewed becoming a father as a rite of passage.

"I always knew I wanted to be was a father," he said on The Tonight Show Starring Jimmy Fallon. "You become a father, you're immortal. Your lineage lives on, you pass it on."

The actor has written a memoir titled Greenlights. He describes it as an "aspirational book" about an approach to life.

"It's stories, insights, philosophies," McConaughey said, saying it is like "taking a spaceship to Mars without needing a pilot's licence".

He added: "There's a lot of good wisdom in it but advice is touchy. Nobody really wants to hear advice from a celebrity and nobody likes to be told what to do, especially me".
