Based on a survey by top2040, here are the top Star Wars quotes.
1 - "May the Force be with you..." said first by Obi-wan Kenobi, and later by many other characters. This tops our list of best Star Wars quotes, is the most often repeated line, and is the grounds for "May the 4th" being Star Wars day.
2 - Yoda comes in 2nd place: "Do, or do not. There is no Try."
3 - Darth Vader gets our 3rd most popular quote: "Luke, I'm your father!' This has been parodied more than any other movie quote.
4 - Han Solo: "I've got a bad feeling about this."
5 - Darth Vader: "The Force is strong with this one." (the Top2040 favorite)
6 - Princess Leia, referring to Chebacca: "Will somebody get this big walking carpet out of my way!"
7 - Referring to the Millenium Falcon, Leia says: "You came in that thing? You're braver than I thought."
8 - C3PO : "R2D2! You know better than to trust a strange computer!" along with the often heard "R2D2, where are you?" The golden droid was always losing this friend.
9 -Leia: "I love you." Han: "I know"
10 - Han to princess Leia, "Of course, your worship...." and "No reward is worth this."
