It's Not Baron Barracuda

 

 (imdb)

BARRACUDA-1970-In some hick Florida town, full of grouchy people, Oceanographer Mike (Wayne David Crawford) tries to prove a local chemical company, Jack Chemical is polluting the water. The owner (Bert Freed) has him arrested but nice guy sheriff (BLOOD FEAST's William Kerwin) lets him go. Mike and the sheriff's daughter (Roberta Leighton) investigate. Swimmers are being killed by some deadly fish. When loads of dead fish wash up on shore, the sheriff becomes concerned. Meanwhile, men in dark suits wander around suspiciously. A local doctor (Jason Evers from THE BRAIN THAT WOULDN'T DIE (1962)) helps the sheriff determine that killer barracuda are on the prowl due to chemicals from the plant. A reporter (dressed to look like Carl Kolchak) also investigates. Another guy in a suit (Harry Kerwin) kills people too. But the doctor is actually behind The Lucifer Project, a government experiment to control people through their blood sugar levels. 

This killer fish conspiracy film by director Harry Kerwin with underwater scenes directed by star Crawford (who also co-wrote and co-produced) is pretty bland.

Wilde In The Future

 

(IMDB)

NO BLADE OF GRASS-1970-When a mysterious virus nearly wipes out England's agriculture and pollutes the water, a man, John Custance (Nigel Davenport) and his wife Ann (Jean Wallace) and two kids along with their friend Roger (John Hamill) head for a farm in the country. Along the way they pick up the violent Pirrie (Anthony May) and his flirty wife Clara (Wendy Richard). It doesn't take long for the group to descend into killing and stealing. The wife and daughter are raped by 3 creeps and their cars and goods are taken by a town. Meanwhile the government has fled and the world is descending into cannibalism. Things don't turn out like they planned and there's a wild fight with a motorcycle gang. They make it to the farm but problems arise with David (Patrick Holt) John's brother. 

Basically this treats a future calamity in pretty depressing chilling dog eat dog terms (more so then say PANIC IN THE YEAR ZERO which at times GRASS imitates). Where as Ray Milland's character worked against a breakdown in society, John readily accepts it's kill or be killed and might makes right (especially in the climax). There are a few lapses but overall this is an ahead of its time feature directed and co-written by actor Cornel Wilde (he and a lead actress Wallace were married in real life) especially with the world situation today.
