Andy Dick is one of those performers who could be incredible. When someone sees his earlier work, one could compare it to early Micheal Richards, before and in the early years of Seinfeld.
He was chosen as the son of Maxwell Smart in the 1995 version of Get Smart. Unfortunatly Andy Dick was a poor choice who brought too much uniqueness to the part. He couldn't be given a roll and sadly the series was canceled after only a handful of episodes. Luckily Andy Dick got attached to a fledgling show with Phil Hartman, and Dave Foley.
Andy Dick started off slowly, and with in a couple years gathered almost a cult following, becoming almost as popular as the show's two principles. He brought a silliness and a comedy element that the show sorely needed, one that set him up for his future.
Unfortunatly this show was fated to fall after the death of Phil Hartman. The show slowly fell apart as there wasn't a strong enough lead to replace him. After this show Andy dick slowly floated from project and this is where his downhill slide started.
He even attached to the MTV network for the Andy Dick Show, as well as his own reality/spoof show "The Assistant". Sadly both of these made his already inflated ego spin out of control. It seemed that Andy Dick felt the need to be flamboyant in all aspects of his on screen performances, and it has ruined was was otherwise a bright future.
Luckily he has a part on a show on ABC which seems to be working for him, but sadly this is not indicitive of his original talent all those many years agos when he was just starting out.
