def get_author(data, search_author):
    # using here argument unpacking
    for movie, (year, author) in data.items():
        if search_author == author:
            print(movie, year, author)


get_author(movies, 'Steven Spielberg')

Without argument unpacking:

def get_author(data, search_author):
    # using here tuple unpacking
    for movie, value in data.items():
        year = value[0]
        author = value[1]
        if search_author == author:
            print(movie, year, author)


get_author(movies, 'Steven Spielberg')

If you want to sort them by X, use the sorted builtin function together with the key argument.

def by_author(item):
    '''
    Returns the author of an item
    '''
    return item[1][1]


def by_year(item):
    '''
    Returns the year of an item
    '''
    return item[1][0]


def by_movie(item):
    '''
    Returns the movie of an item
    '''
    return item[0]


def get_author_sorted(data, search_author, sort_by):
    for movie, (year, author) in sorted(data.items(), key=sort_by):
        if search_author == author:
            print(movie, year, author)
