Tony Danza says it's been 40 years since Taxi debuted, and he's up for a reboot if asked.

Why not? All you need is Danny DeVito to go for it... without him? It's not going to work.

the original cast:

Judd Hirsch.............Still alive, was just in a tv series, so, still enjoys acting in tv series. Infact, that's all he does are tv series

Danny DeVito........ Still alive, still doing tv and movies. That evil character he played was so fantastic for the humor needed to anchor that tv show about taxi drivers

 Marilu Henner...... . still alive, still doing tv

 Andy Kaufman.......dead, but, really not a character needed for the show a 2nd time around

J. Alan Thomas....... dead, do you even have any idea what he looked like? Or did? Nope.

 Christopher Lloyd..... . still alive, still doing tv, a must for the show... omg, imagine what story arc they could do with Rev Jim Ignatowski now

 Randall Carver..... . still alive, still doing tv

 Jeff Conaway.......... dead.
