Lemon cypress trees do well in pots and grow quickly. Bamboo like Fargesia 'asian wonder' would work well and grow fast inot a thick screen, evergreens like Loquat, Camellia etc will also work.
Failing that, just put up a fence in front of theirs on your side of the boundary. No one likes sitting facing neighbours!
