And you also need to know what colour light sabre Luke Skywalker wields in Return of the Jedi and Emperor Palpatine's real first name.
With MultiChoice's pop-up Star Wars channel on DStv channel 109 which still run until 13 September, M-Net created an immersive online site at mnet.tv/starwars.
Here anyone (droids excluded) can do a Star Wars quiz which is surprisingly more difficult than what it looks.
While people on national census forms the world over jot down "Jedi" when asked their religion, you can't really do that unless you score high on M-Net Movies' Star Wars quiz where your midichlorian count climbs as you answer questions correctly.
Up for grabs are prizes like tickets to the Johannesburg movie premiere in mid-December of the next Star Wars movie, Star Wars: The Force Awakens. (No tickets to the premieres in Cape Town, Port Elizabeth and Durban, M-Net tells me.)
Who sold R2-D2 to Owen Lars? If you don't know, you haven't watched the Star Wars movies enough.
People taking the quiz has 30 seconds to answer each question.
Get ready for some surprises as well: In M-Net Movies' Star Wars quiz there's some questions which will leave quiz takers momentarily baffled like the funny "Who shot first?" - one of the issues that has been much debated in Star Wars lore over the past few decades.
Even those Jawas not strong with the Force can win. Besides "other goodies" there's 6 DStv Explora decoders that can be won simply for completing the Star Wars quiz and entering the competition.
People can replay the Star Wars game as many times as they like to try and better their midichlorian count, although the quiz questions change with every try.
"M-Net has a strong digital presence with all its biggest properties and the Star Wars online experience is enhancing the content in a fresh way - what you would expect from M-Net Movies," Lani Lombard, M-Net's head of publicity told TV with Thinus.
