Mine is probably Blast From The Past a silly romantic comedy that was on TBS every Sunday for years and the tv would be on so it would be running in the background for whatever I was doing. Brendan Fraser, Alicia Silverstone, Christopher Walken, Sissy Spacek, Dave Foley, Joey Slotnick. Nathan Fillion. etc. A nicely structured entertaining movie but a 5/10 for me.
Of the movies I have intentionally watched, I would think that my most watched would either be Citizen Kane or Run Lola Run.
Although I have may have seen La Jetée more than that but I am not sure that counts as it is a short.
Not one movie, but the Star Wars trilogy.
They're some of the first movies I remember watching as a child. My dad rented the laser discs from Blockbuster, and I'll never forget the covers. Blue Star Wars with Vader on the cover, purple Empire with a storm trooper, and red Jedi with Yoda. Those huge discs will always be the definitive editions for the movies to me.
Later, my dad took me to see the new special edition of Star Wars at the old theater uptown. Watching the attack on the death star on the big screen was awesome as a 5 or 6 year old. It's still my favorite of Lucas' "enhanced" scenes.
Those films instilled in me a love for epic stories and trilogies following a hero's journey. LOTR and TDK trilogy would scratch those itches later.
But I always managed to keep watching the trilogy throughout the years, and now it's become tradition to watch it at least once a year. Hell, I might have to watch it soon now.
Of course, they're pretty much played out for me now so I could end up catching up with to them with 8 1/2, since its my favorite classic, and The Tree of Life, as it's my favorite.
I've also watched Fury Road about 5 times. That caught me off guard, actually. I just keep finding myself perfectly in the mood for the stunts and action.
