LOL you've just described the opening of the 2012 rom-zom-com A Little Bit Zombie. And then there's the Sucker which is supposed to feature zombie mosquitoes, but after reading the description I don't think it qualifies as a zombie movie.
This is one thing I hate about the internet age. See, back in the day, if you were fairly creative, you could delude yourself into thinking that you had some original ideas. Now, as soon as you have what you think is an original thought, you’ll find out five minutes later that someone already beat you to it.
