Attack Of The Killer Tomatoes. 1978.
A group of of scientists band together when normal tomatoes go on a killing spree.
Right from the start when it mentions Alfred Hitchcock's The Birds you know this film will never achieve to be better, even with the title, salute to the 50s B movies that some are better than this, daft, cheesy acting, stupid visual/special effects, i'm pretty sure you see a giant tomato on a trolley improvising that it's moving, yet still found it a laugh.
