Dictionary/List Homework

[ImLearningPython]

While working on this, I have it working as it should with one exception. Under the dictionary, there is two list that has 4 values instead of 2 values. When I run the program it isn't printing the right values together for just those two year. I have messed with this for days and can't seem to figure out how to get it to print correctly.

movies = {2005: ['Munich', 'Steven Spielberg'],
              2006: ['The Prestige', 'Christopher Nolan', 'The Departed', 'Martin Scorsese'],
              2007: ['Into the Wild', 'Sean Penn'],
              2008: ['The Dark Knight', 'Christopher Nolan'],
              2009: ['Mary and Max', 'Adam Elliot'],
              2010: ['The King\'s Speech', 'Tom Hooper'],
              2011: ['The Artist', 'Michel Hazanavicius', 'The Help', 'Tate Taylor'],
              2012: ['Argo', 'Ben Affleck'],
              2013: ['12 Years a Slave', 'Steve McQueen'],
              2014: ['Birdman', 'Alejandro G. Inarritu'],
              2015: ['Spotlight', 'Tom McCarthy'],
              2016: ['The BFG', 'Steven Spielberg']}

options = input('Choose a sort option: \n')
title_list = []
if options == 't':
    for key in movies:
        i = 0
        while i < len(movies[key]):
            title_list.append(movies[key][i])
            i += 2
    set_title = sorted(set(title_list))
    for title in set_title:
        print('%s:' % title)
        for year, value in sorted(movies.items()):
            if title in value:
                print('\t%s, %s' % (value[value.index(title)-1], year))
        print()
