4/5 Not really what I expected
  by Willem De Blank (Quito, Ecuador)
This movie is actually not really what I expected but it is a good movie.
I liked the story it is about Sammy "the Bull" Gravano and it is until the moment he became a rat and went into the witness protection program.
The story is OK the rest is acceptable. Overall a good enjoyable movie

5/5 Must see
  by Aaron Heaton (Charlottesville, Va)
This is an amazing portrayal of sammy gravano! Tom sizemore is nowhere near as good as armande assante Who played john Gotti on The HBO drama "Gotti". but truly a good all around movie. anyone who idolizes john gotti or is somewhat infatuated with the Italian American Mafia should definately see this movie it really puts things into perspective and changes your original thoughts about the so called King Rat Salvatore "sammy the bull" Gravano.

5/5 Not on DVD!!!!!!! What!!!!!
  by Anthony Rodriguez (Houston, Tx USA)
I cant believe this movie is just going to be released on DVD, what a shame. It should have been released a long time ago as far Im concerned. This one of the best Mob movies ever right in between Godfather and Goodfellows and Donnie Brasco. What really dissapoints me that it is going to be released in full screen, who ever is putting this out should really consider a wide screen format. Tom Sizemore does a better job then Armand Assante in portraying Gotti (although I thought Assante was pretty good in the HBO movie Gotti). Trust me if you like Mob movies and crime dramas this is most definitely for you. The story telling is so compelling that your eyes will be riveted to you tv screen. By far it is deserving of 5 stars, now do yourself a favor and buy it or at the very least rent it you wont be dissapointed.

5/5 A MOB MUST SEE
  by Compusurge (New York City)
Witness to the Mob is an absolute MUST SEE for ANY fan of Mob films and NY mob history. A dramatic retelling of the story inspired by the NY Times best selling novel Underboss, "Witness" recounts the rise of John Gotti and his right hand man Sammy 'the bull' Gravano within the NY crime scene and the Gambino family.

Packed with stars known to this genre (three from the Sopranos), the film portrays the violent times with a sense of great realism. Told from Sammy Gravano's side of the table, it contains a sense and perspective unlike other films, for Gravano was not 'the dapper' Don, he was the man who made things happen in his own way.

The style is a narrative one in the same way Goodfellas is... in this case, the narrator is Nicholas Turturro in the lead role of Gravano. It works wonderfully as it brings you into the storyline on a personal level, providing insights as the film moves along.

No collection of mob films should be without this one, and I, for one, am thrilled it's finally making its way to DVD!!!
