Remember Coach Bolton? He was Troy Bolton's dad, duh.
He was played by Bart Johnson. Fun fact: Zac is almost as old as Bart was when they filmed this movie! But that's neither here nor there.
What is *here and there* is that Bart Johnson aka Coach Bolton is literally the most supportive person in the world of Zac Efron. I noticed whilst looking at all the comments on Zac's Instagram pics and realized that Coach Bolton/Bart Johnson comments on all of them. All of 'em!!!!
Bart loves Zac's crappy and blurry pics:
Bart loved when Zac supported his brother at the Boston Marathon.
Bart loved Zac's blonde wig:
Bart loved this photo:
Bart loved it when Zac got out of LA and into nature.
