Remulak aliens, Beldar (Dan Aykroyd) and Prymatt (Jane Curtin), were on the search for a planet to conquer when they mistakenly ended up on Earth. Never the less they set about discovering all about life on Earth especially as they discover they are soon to be parents. But unfortunately after finding work Beldar requires a fake identity and this alerts INS Deputy Commissioner Gorman Seedling (Michael McKean) who makes it his mission to capture them and send them back home.
I have two things to say when it comes to "Coneheads". The first of which is as a piece of entertainment, a sci-fi comedy it is one of the least funny movies I have had the displeasure to watch. From accents which grate within minutes to gags which don't even gain a groan let alone laugh it just doesn't work. Basically this feels like one of those SNL movies where the original sketch idea probably worked as a one off or a regular feature but as something which could sustain an entire 90 minutes just feels desperate from start to finish.
But secondly; whilst "Coneheads" rarely raises a laugh from the intentional gags it does have a certain appeal. That comes from playing the actor spotting games with numerous faces showing up many of which who went on to bigger and better things, although some might debate that. As such amongst the familiar stars there is a young David Spade, Adam Sandler, Ellen DeGeneres and Garrett Morris.
What this all boils down to is that "Coneheads" rarely entertains in the way it intends with a storyline which feels weak and many a gag which falls flat. But the fun of spotting all the familiar faces amongst the cast gives this a bit of fun.
