I have this considerations because checking both movies, we can notice they share many things such as the source movies used for both. I mean the original taiwanese movie used for Majestic Thunderbolt has almost the same cast seen at the source movie in Mission Thunderbolt: this is Chen Kuan Tai & many of the supporting cast. The same can be said for the new fotage because Philip Ko, John Ladalsky & other people from Mission Thunderbolt are again in Majestic Thunderbolt.
Majestic Thunderbolt was edited as Magnum Thunderbolt in some European countries. Later IFD would release the real Magnum Thunderbolt
The screenplay at both movies is very similar as well, so we have two rival gangs trying to destroy each other in the original movie then we have Richard Harrison in the new fotage fighting different villains till he has a final duel facing Philip Ko.
The Thunderbolt saga movies could have been become into real IFD classics if they had had more careful doing their work
Both movies are so similar that we could tell Majestic Thunderbolt may be a remake of Mission Thunderbolt where Jonathan Stierwalt is replace by Richard Harrison in his first work for IFD. Majestic Thunderbolt is to Mission Thunderbolt what Drunken Master was to Snake in the Eagle's shadow.
Some fotage from Majestic Thunderbolt showing Philip Ko painting & having sex with a tied girl was later used in Scorpion Thunderbolt when Richard Harrison is having sex with a not too pretty girl in a cinema.
While Mission Thunderbolt is still on IFD catalog for its international sales, Majestic Thunderbolt as it happened to Inferno Thunderbolt, Scorpion Thunderbolt and even Ninja Thunderbolt is not longer on Joseph Lai's catalog. I would really like to know the reason. So if you get a copy of this movie, take it as missing pearl since it can't be found easily or the master has been destroyed as it happened to many taiwanese gangster films shot between 1979 -1983 .
Spanish video art cover. as many IFD movies, Majestic Thunderbolt was edited in Spain twice. The alternate title was Operacion Majestic
Majestic Thunderbolt has a very curious detail to offer us: At the begining, we see Richard Harrison, John Ladalsky & a nameless actor who are attacked by a couple of killers carrying axes. One of these killers is played by Tommy Cheng Kei Ying who would become the main director of Filmark ninja/ action movies just a couple of years after his supporting role at IFD's Majestic Thunderbolt.
In some countries Majestic Thunderbolt was edited as Magnum Thunderbolt. This could create some confussion since Magmun Thunderbolt was the international title used by IFD for its relesase of A Man from Holland another movie starred by Philip Ko & Chan Wai Man that look like an IFD movie due to the filming skill & because many of the IFD regular locations were used on it as well.
