Rebels With A Star Trek-ish Score
2 September 2007 | by See all my reviews

The first season of classic Star Trek had some great Alexander Courage scores but the second season was mildly damaged by the too-loud or too-light-hearted scores of composer Gerald Fried. Well guess what, Fried also scored two episodes of LIS and Collision Of The Planets was one of them. His LIS music here is just as light hearted and even more loud but the episode itself is so insane that the Fried score is almost welcome. We needed new music at this stage in the season.

LIS year two was silly nearly every week but year three only went silly sometimes, like this hour, and this made the over-the-top camp less of a problem. Granted, Collision is not the best of year three (the humour in Two Weeks In Space was better), but if you go along with the humour of Jonathan Harris and the rebel gang, well, you might have a fun Bewitched/I Dream Of Jeannie-type joy ride. Who could not laugh at the end bit in space where the "bike riders" over-take the Jupiter 2 "Get that heap off the road, little masters". Interestingly, Don and John respond to that crazy line in a deadly serious way????

Other highlights include the teaser (note The Time Tunnel props) and the bits where John/Don go to the rebel gang campsite and have a few clash of culture exchanges. Some male viewers will find the young female rebel rather hot to look at.

Added note: Voyage to the Bottom of the Sea submarine props are used in an imaginative way.
