I watched taxi a lot back when it was on.
A shame about his downfall with drugs & alcohol.

A true shame.

I loved Taxi.He also played a great character on one of my favorite sci-fi
shows,Babylon 5.

I saw him on maybe a reality show or something similar and it was obvious he was strung out. My thought was he can't find work, he starts daily disabling substance abuse , it shows in his demeanor so nobody will hire him just based on how he looks and acts so he goes further into depression over no work and thus the downward spiral. A shame to see it happen but its very common amongst actors who had a good part or two but never broke through as stars.
