Log in to your Netflix account with your name and password. You will be taken to a page with movie recommendations based on your previous rentals. At this point, search for movies to add to your queue by either entering a title into the "search" box or by browsing genres. When you find a movie to add to your list, click the red "Add."
Step2
Click the tab at the top of the page that says "Your Queue" once you have selected your movies. You will be taken to a page that shows the list of movies you want to check out. You can now put them in the order you'd like to see them. For example, if you suddenly realize that you don't want to rent "Fever Pitch" next and you'd rather see "Mean Girls" this is the page where you can fix the order.
Step3
Click on the small blue arrow pointing up or enter the number "1" in the box in the "Priority" column to move a movie to the top of your list.
Step4
Click the box in the "delete" column and then hit the "update your queue" box to delete a movie from your queue. You can always add movies back if you change your mind.
Tips & Warnings
If you're renting a TV series but would like to mix it up with movies, you can arrange to get a disc of the series and then a movie.
