I am overjoyed to report that that Rocky VI (simply titled 'Rocky Balboa') is in post-production.
Here is a shot from the latest film, taken Jan 19, 2006:
According to IMDB Stallone is 60 years old!
The franchise tailed off with Rocky V, so I don't have high expectations, but since the series was an integral part of my growing up I know I will enjoy the 6th installment.
PS - My VHS Rocky collection was about to go to the charity shop, but I think I'm going to have to hold on to the tapes for one last viewing.
