Not at all. "Universal Soldier 2: Brothers in Arms" (1998) and "Universal Soldier 3: Unfinished Business" (1999) are set in a standalone continuity loosely based on the first feature film, "Universal Soldier" (1992). So you don't require to watch the two TV movies produced by Rigel Entertainment in order to understand the events of "The Return".

Not anymore. "Universal Soldier: Regeneration" (2009) has retconned "The Return" to the point none of the events of the movie ever happened in the main Universal Soldier continuity. "The Return" is now a self-contained alternate universe.

• For instance, in "Regeneration" it is strongly hinted that Luc Deveraux never reverted to the "human" state, nor such process is ever possible to accomplish.

• In "Regeneration" it is apparent Luc never had a daughter as once depicted in "The Return", nor he seems able to psychologically adjust to human life again and mate as a "normal" people.

• Even more importantly, in "Regeneration" it is officially stated that the N.G.U. project ("The White Tower") is just the second attempt at producing UniSols, not the third one.

• Finally, you can notice in "The Return" Luc displays white/gray streaks in his hair that are nowhere to be seen in "Regeneration".

Generally speaking, "Regeneration" totally ignores "The Return" and even contradicts it.

Yes, but it's a different role. As further proof "The Return" is set in an alternate universe, while here White plays the computer S.E.T.H. embedded into a "Super UniSol" body, in the original movie he played a soldier fighting in Vietnam, during 1969.

UniSols are revived organisms, not "zombies". They are not dead anymore, and still retain their vital signs and functions, including mating and reproduction. Despite in "The Return" Luc keeps referring them as "dead", it's metaphorical. They are 100% alive.

According to the writer of the movie, and heavily hinted by some dialogues (especially when Luc confronts a delta unit UniSol gone berserk at the beginning of the movie), it seems like he got some residual UniSol physical powers like enhanced strength, speed and resistance. This is further backed-up by the final confrontation with S.E.T.H.

It was a domestical flop, but not as bad as some claimed in the past. The movie's real budget was 19 million dollars. It grossed over 10 million dollars in the States, and according to some rumours it went to cash at least 20 million dollars in Europe and Japan. Also, video rentals were massive (14 millions of dollars only in the States) and the film had very good DVD sales. So the movie made some good business, only not as much big as the first feature film.

No. Van Damme just wore the UniSol 2500 uniform and gear for some production stills, and one of them worked as template for the movie poster. Luc Deveraux never wore the uniform during the movie, nor he had some reason to do so.

Although the movie itself isn't all that violent, two short sequences had to be cut for the UK DVD, in order to follow the strict guidelines of the BBFC, but it is barely noticable.
