Sequelly

Apperantly the didnt want too much money. The sequel was a direct to dvd release called S.W.A.T: Firefight. I havent seen it, not sure it its any good.

In its day it was a pretty expensive film that made some money, but not mega amounts. So they went cheap on the sequel, which came quite a few years later.

Yeah I don't know if I'd call or consider that to be a sequel. It had NO hallmarks of swat, and only seemed to be using the name and fame of the actual movie.
No a real sequel in my book.

if all the original cast return I definitely think there could be a sequel that could be awesome. I had an idea for a sequel where a terrorist group take over an la court house to use judges and council officials for hostages. The SWAT team take them down & they end up in prison with Montel who is using his money & influence to escape. He offers them freedom under the provision they start a war with the LAPD & take down Hondo's crew. there's more to it, but you get the general idea

I doubt they could get the entire cast back, but that would be the way to go.
