Zac Efron reveals iconic High School Musical dance was actually improvised

Zac Efron has admitted one of his most iconic High School Musical dance sequences was entirely improvised.

The 36-year-old American actor shot to fame off the back of 2006 smash hit film High School Musical, which then became a franchise - and we were later treated to HSM2 and HSM3.

Efron starred as popular heartthrob and basketball star Troy Bolton, who falls for Gabriella Montez (Vanessa Hudgens), a much quieter and academically talented transfer student.

Viewers of HSM went absolutely crazy over it at the time - and a fair few of us were probably guilty of scrawling 'Miss Troy Bolton' in the back of our notebooks.

Efron's acting career went from strength to strength as a result of his HSM fame, and he has since starred in titles such as 17 Again, The Iron Claw, and even played depraved serial killer Ted Bundy in Extremely Wicked, Shockingly Evil and Vile, which earned him a lot of critical praise due to his steely performance.

Despite the HSM franchise being a spate of teen movies, Efron has refused to shy away from his involvement in the films, and instead embraces his humble beginnings.

And he recently opened up about one of the most memorable dance sequences of HSM2 - that golf course scene.

For those who are unable to place it in memory - it's when Troy stomps across a golf course, feeling sad and frustrated, and bursts into song and dance, thus creating the bop 'Bet On It'.

Remember: "Did you ever / lose yourself to get what you want... / did you ever / get on a ride and want to get off?"

I mean, how could you forget?

It has created a lot of memes since, mainly due to the exaggerated hand and arm movements.

Despite the 10/10 choreography and tension that you can feel through the screen, Efron has revealed the magic is all down to him and him alone.

He told Still Watching Netflix that director Kenny Ortega had told him they 'didn't have a concept' for the song, which led to the star taking matters into his own hands.

He said: "That was all improv. And we shot it, I think the whole song, in like three hours.

"When we shot that, we just had no ideas for what to do on the day.

"The director, he was like, 'Dude, we have no concept for this song. What do you want to do?' I was like, 'I don't know, we're on a golf course.'"

Can we please get him in a directing role ASAP?
