I'd go with Rob on this one. Under Siege was a really good movie, but Segal had alot of real professional help on this one (including Tommy Lee Jones, a sober Gary Busey, Colm Meaney of STNG fame, Andy Romano, old sci-fi standard Nick Mancuso, the highly underrated latino Raymond Cruz, Bernie Casey, and the surprisingly believable Miss E)
In most of his other movies, his "help" came from talent of the caliber of Kelly LeBrock, best known (if memory serves)for her role in "Weird Science".. other than visuals, there's not much to take your mind off Segal's bad acting... even Keenan Ivory Wayans couldn't cover for him in the Glimmer Man
