The Movie: Dead of Night (1945)
What Is It?: The first great horror portmanteau set the standards to which all subsequent horror portmanteau’s adhered, including its uneven nature. But episodes about a haunted X-mas party and a rather independent ventriloquist’s dummy deliver the goods, and the wrap-around story is the greatest in the history of horror portmanteaus.
Why Today?: Today is the longest night of year…plus the Christmas episode fits this week's holiday theme.
