if you have tyson the movie 2 disc knockout edition then you dont need to buy this. the knockout edition has a movie plus a extra hour of action. This dvd is mis-selling as it states there is three and a half hours of action when there is only two and a half hours and as i said its the same as the knockout edition but is cut and has less. Really a waste of time so dont be fooled as this is previously released just repackaged. Please dont waste your money.
