I have become a big fan of 1970s disaster movies. There is just something wonderful about a great big cast full of classic movie stars and up-and-comers all facing off against some ridiculous disaster. Airport (1970) essentially launched that genre and created most of its tropes. They released three more Airport movies, all of which had very little to do with each other, and were sometimes only barely connected to an actual airport but did all star George Kennedy as Joe Patroni, a mechanic/pilot/administrator.  Kino Lorber recently released them all in 4K, and I reviewed them for Cinema Sentries.  They have now released a boxed set of all four, but I got them individually.

You can read them in order here:
Airport (1970)
Airport 1975 (1975)
Airport ’77 (1977)
The Concorde…Airport ’79 (1979)
