You can't really approach this as a remake of the classic 'The Day of The Jackal.' Though broadly similar, the entire feel of the two films is incomparable. And suspense thrillers are all about "the feel" aren't they?
The story is pretty standard fair - a super villain assassin (Willis) is going to make a big kill using a huge weapon and leaving a trail of bodies along the way. Gere, an IRA soldier (jailed for "terrorism") is brought on as consultant because he is one of the few people who has seen 'the Jackal", and given a few vague promises in exchange for his help. As it turns out, Gere has more than just knowledge - he has a vendetta. Poitier oversees Gere and the investigation of Willis, and comes to realize that Gere is the only hope of stopping him.
I like Sidney Poitier, Bruce Willis and Richard Gere, so I was predisposed to like this film. I was neither very surprised nor disappointed. The Jackal is entertaining and the performances are strong. Poitier is always a class act, and Willis and Gere have terrific anti-chemistry. There's nothing wrong with the cinematography or directing, and the pace of the film, though a little breathless, is fine. Regardless, the story-line never reached much beyond the ordinary thriller fare. Making a truly great thriller requires either doing something really original (very hard to do) or using a truly inspired script. This film's script is decent, but the story line could have used a little more careful thought and a bit more complexity.
