The two big box office films are also very different from each other, so should draw substantially different crowds.
Rio has already debuted to incredible numbers and reviews overseas and has shown the world that the little blue macaw has what it takes to make box office gold.
Rio is expected to bring in more than $45 million this weekend at the box office - largely due to its amazing early reviews and great marketing campaign.
Scream 4 is also expected to bring in a lot of money for the fledging movie industry. The first three films in the franchise have grossed more than $500 million and still prove to be very successful.
This weekend, Scream 4 is expected to bring in around $40 million.
Rio: When Blu, a domesticated macaw from small-town Minnesota, meets the fiercely independent Jewel, he takes off on an adventure to Rio de Janeiro with this bird of his dreams.
