Topics/themes needed for a new challenge

I am about to embark on a challenge to watch 1 movie each day/night for 7 days/nights on a theme and then switch to another theme. I dont particularly want broad themes more likely to be hybrids

I am looking for suggestions possibly along the lines of...

7 days/nights of Asian horror re-makes...if there are 7?
7 days/nights of giant monster movies
7 days/nights of Gene Hackman movies
7 days/nights of films with colours in their titles
etc

any other ideas?

ok - obviously not a glimmer of interest - so bumping

I started this and have done a 7 Days Of 80s Horror and in the process of completing 7 Days Of Kids Animations
