I am very happy to see Juno doing so well.
Firstly, the box office. Juno only had a budget of $2.5 million. The $100 million domestic was reached this weekend and the movie has not launched in most countries yet. Just Australia, Canada, and the US.
Secondly, the awards. Four Oscar nominations: Best Picture, Best Director - Jason Reitman, Best Actress - Ellen Page, Best Original Screenplay - Diablo Cody.
Thirdly, the reviews.
Rotten Tomatoes has Juno at 93% based on 154 positive and 12 negative critic reviews; the user rating on Rotten Tomatoes is 89% based on 1023 positive and 114 negative user reviews.
On IMDb, Juno has an 8.4/10 rating based on 34,511 ratings, putting it #117 overall on IMDb.
Congrats to Jason Reitman, Diablo Cody, Ellen Page, and the rest of the cast and crew for making a fantastic movie with a small budget.
