Here's Your Daily Dose Of Zac Efron Going Shirtless Under A Waterfall, Because Obviously

DO go chasing waterfalls if the result is a shirtless Zac Efron goofing around with his somehow equally hot younger brother. The Efron bros treated their thirsty fans to some birthday celebration photos that just happened to also look like perfect calendar shots. Zac's younger brother Dylan Efron turned 27 on February 6, and it was a very happy occasion for the brothers and their fans:

Oh my Troy! Zac Efron knew exactly what he was doing with that post. You can tell because he turned it into a gallery of photos, with four images of the goofy shirtless brothers roughhousing in the water. Here's another photo:

The Greatest Showman, indeed. That birthday post has more than 3 million likes and counting. They probably should've used it as an ad to sell something -- beyond the unexpected attractiveness of Zac Efron's younger brother. The younger Efron probably got a boost of Instagram followers after these shots. His bio lists him as a filmmaker, writer, athlete, and outdoors enthusiast.

When fans were finished drooling, or at least on a break, they wished Dylan a happy birthday. They also got busy debating the physical merits of both brothers -- is Dylan perhaps even more attractive than Zac? Just reporting what's out there in the shallow end of the comments, folks, don't shoot the messenger!

Dylan Efron aside, for a moment, this is an interesting time for Zac Efron. The now 31-year-old actor shot to fame with High School Musical and Hairspray, and recently stayed in the musical zone with The Greatest Showman with a comedic action break with Baywatch. But he's also dabbled in some serious drama, and he's headed in that direction again with Extremely Wicked, Shockingly Evil and Vile. Efron plays Ted Bundy in that crime thriller about the serial killer.

Because Zac Efron is a legit snack -- even with a crazy new hairdo for another role -- many worried that casting him as Ted Bundy would only glamorize the killer. But Efron recently said that won't be the case. He felt a "responsibility" to make sure the film didn't celebrate or glorify Ted Bundy.

Extremely Wicked, Shockingly Evil and Vile is headed to Netflix, which is already home to plenty of serial killer attraction with YOU and multiple docuseries. It's not clear yet exactly when the movie will arrive on Netflix, but here's what's on the streamer in February 2019. And here are more movies headed to theaters in 2019, including Zac Efron's The Beach Bum, starring Matthew McConaughey.
