I suggest Craig Armstrong for some action-pack film scores. Particularly, Kiss of the Dragon, Plunkett & Macleane and The Bone Collector. Also Hans Zimmer's Batman Begins is currently one of my favorite action soundtrack.
Here are suggestions:
Jerry Goldsmith's "Total Recall"
Toto's "Dune"
David Arnold's "Stargate"
James Horner's "Aliens"
Thank you for these suggestions

This Craig Armstrong seems to be a very good composer; while looking for the scores you mentioned I found that he also wrote for
Elisabeth - The Golden Age, a great film with some great music.
Total Recall and
Aliens I already have (both as extended/complete versions), the
Stargate score I constantly forget to buy (and I love Arnold's
ID4 score) - thank you for the heads-up
In terms of big bombastic scores, the "Pirates" soundtracks by Hans Zimmer are great, particularly "The Kraken" from "Dead Man's Chest". As far as "rousing" scores go, David Arnold's scores for "Independence Day" and "Stargate" were very good. My personal all-time favorite movie score (as people here whom have read my posts can tell you) is Vince DiCola's (he also did the score for Rocky IV) rock/synthesizer score for "Transformers The Movie(1986)" although much of the score, unfortunately, is NOT commercially available but the latest re-release of the soundtrack does have some of his best compositions from the movie.
Ah, yes the
Dead Man's Chest score is fantastic better even than Badelt's score for
The Curse of the Black Perl; too bad Zimmer's score for
At World's End is so dull in comparison.
I love the combination of rock, synthesizer and a full orchestra but I'm very, very cautious with synthesizer only scores... unfortunately Amazon doesn't have any excerpts to listen to...
I'd like to buy the Steve Jablonsky score for the new (although bad) Transformers live (CG

) action movie, but that thing costs over 65 € and I'm not willing to spend that much money even on a good score
Thanks for your suggestions so far.
