“Anaconda” (**1/2 out of four) was a likeably silly comic remake of the 1997 cult classic about a group of guerilla filmmakers (Paul Rudd, Jack Black, Steve Zahn, Thandie Newton, and others) who decide to venture into the Amazon to do a remake of the title film which they describe as “their favorite movie growing up” but soon encounter the real thing and have to run for their lives. Pretty thin stuff but has enough good-natured laughs and zany camaraderie between the leads to make it entertaining although the movie it might remind you most of is “Tropic Thunder.” Ice Cube and Jennifer Lopez have amusing cameos towards the end.
