I absolutely adore the HSM franchise! It’s officially been 20 years since the first High School Musical movie landed on Disney Channel.

So let’s talk about some interesting knowledge linked to these epic movies that still hold a special place in the hearts of millennials everywhere.

Ashley Tisdale and Lucas Grabeel were not friendly on the set of High School Musical at the beginning.

They once had a slight feud between them, which is kind of ironic since they played on-screen twin siblings, and siblings are known to fight with each other in real life.

The good news it that eventually, they did start getting along better.

But Lucas opened up about working with her during the MegaCon convention last year saying, “I was paired with Ashley and she really pissed me off. This girl. I mean this is why she got the job. She was so Sharpay. She literally… We did the scene, we came out, and she’s like, hey so I really wanna like rehearse and go over it again.“

He went on to explain that he was ready to end the workday and go home, but she insisted that they keep going over their scenes repetitively.

Years have passed since they finished filming the movies, and they are on much better terms with each other now.
