Are you talking about Once & Always? It premiered on Netflix last year. I loved it, but I just wish it was a little bit longer. But it was great seeing Zack and Billy again.
David Yost who played Billy, left the show in the Zeo season (season 4) because he was gay, and in his words, got "called faggot one too many times." Dude went through hell before he finally accepted who he was.
Walter Jones did a show on Nickelodeon called Space Cases, and did a lot of shitty movies from what I remember.
