Efron went on to play a number of other roles of a similar nature, including another teen heartthrob, Link Larkin in the remake of the 1988 musical, Hairspray.

Zac dropped his younger, more adolescent Disney image, and began taking on more mature roles.

The teenager we once knew and loved was gone...

And there was now a young man stood in his place - destined to become recognized for his great acting.

Although he began appearing in many more R rated movies...

Including crude comedies such as Dirty Grandpa and Bad Neighbours.

Oh, and we can't forget the time he starred in the Baywatch remake...

Himself and The Rock certainly got a lot of attention.

The actor managed to build his "Baywatch appropriate" body in just twelve weeks when he was in training for the role.

But, in more recent times...

The actor has ditched the abs and ventured into much darker territory with his portrayal of the notorious serial killer, Ted Bundy.

Extremely Wicked, Shockingly Evil and Vile told the story of the demented killer...

And depicted the journey of Ted and his girlfriend, Liz, as he is captured and accused of his many murders.

And, yes, Efron did the impossible...

He managed to make thousands of women suddenly become attracted to a serial killer... Despite his lack of Baywatch abs. If that isn't a skill, we don't know what is.

And people were going that crazy over the new, and "hot" Ted Bundy...

That Netflix had to step in to gently remind everyone that Ted Bundy was, in fact, a demented serial killer and rapist, and that there were plenty of other "hot" actors to drool over on their streaming service.

But this week, some shocking news about Efron's health surfaced.

And fans have been left extremely concerned for the actor.

News broke that Efron had been rushed to the hospital.

According to the Daily Mirror, Efron was rushed to hospital following a "life or death" emergency while filming in Papua New Guinea.

The 32-year-old was flown to Australia.

Following the life or death situation, Efron was flown out to Australia by the medical evacuation crew to undergo immediate treatment.

At the time, he was filming for his upcoming TV show, (ironically) named Killing Zac Efron.

The series sees the actor ditch his luxuries and head into the jungle of a dangerous island - completely off the grid. He'll then try and survive in the wilderness with just a few basic items and the help of his guide for twenty-one days.

The show is incredibly dangerous.

Killing Zac Efron shows Efron truly pushing himself to the limits.

But it seems that while filming, the actor picked up a serious illness.

It has been reported that Efron contracted a "form of typhoid or similar bacterial infection" when he was admitted to St Andrews War Memorial Hospital.

This week, the star has finally broken his silence.

Amidst concerns, the actor tweeted about his recent health scare.

He confirmed he had been admitted to hospital...

But that he has "bounced back" and is doing well. Phew. Thankfully, it's been reported that Efron has been given the all-clear by doctors following a medical assessment. For more on Efron's surprising new movie role, keep scrolling.
