"He's got a hook on them..."
One of those summer thrillers from 1997, this movie was the start of the wave of successful teen and young adult movie actors and actresses.
From this movie you have Jennifer Love Hewitt, who at the time was known for her work on Party of Five, but is know a recognized movie and television actress with her recent success on Ghost Whisperer.
Next you have Sarah Michelle Gellar, who has recently quieted down on leading movie roles and is probably living off her syndication money from Buffy the Vampire Slayer.
In terms of long-term acting potential, you have Ryan Phillippe, who has not only appeared in some critically acclaimed films over the past decade, but has shown that he can act in some serious roles, action movies, and even dark comedies. He has showcased the most versatility and could end up being the most recognized member of this film cast.
The one with the least success thus far is probably Freddie Prinze Jr. I believe he was originally in line to become the next Keanu Reeves, but his time might have passed to supplant Reeves in the roles in which solid acting and even facial expressions are not necessary. Prinze Jr. has chosen some poor roles since this movie, especially with a recurring role in the Scooby Doo franchise... yikes!
Other cameos from semi-stars you might recognize are Bridgette Wilson (Mrs. Pete Sampras), Johnny Galecki (known for his roles on Roseanne and the clever comedy The Big Bang Theory), and even Anne Heche, who seems grossly out of place with these younger stars.
In the end, they made a sequel to this film, which they only made because of the success of the original. The cast and popularity of these teenage / young adult actors is what sold this movie... not the plot or storyline. I also discovered that they made another sequel sans Hewitt - probably a straight to video type of thing, but hopefully, with some nudity. Hey, you gotta have a positive somewhere... this is a 14-A horror movie. Back when I was 17, this was a total rip-off.
