As hint says - it's a key in a movie['box office'] dict

from imdb import IMDb

client = IMDb()
movie = client.get_movie('4154796')
print(movie['box office'])
print(movie['box office']['Cumulative Worldwide Gross'])

Output:
{'Budget': '$356,000,000 (estimated)', 'Opening Weekend United States': '$357,115,007, 28 Apr 2019', 'Cumulative Worldwide Gross': '$2,796,274,401, 12 Sep 2019'}
