According to Star Wars lore, C-3PO didn’t meet Han Solo and Chewbacca until the events of A New Hope. But even that fact couldn’t break Anthony Daniels’ four-decade streak. Daniels’ C-3PO has made at least a cameo in each of the previous Star Wars movies. However, Daniels took on a brand-new role for his cameo in Solo: A Star Wars Story.
SPOILER ALERT: There are minor plot points below for Solo: A Star Wars Story. Come back after you’ve seen the movie!
Entertainment Weekly had a breakdown of Daniel’s Solo cameo and the background of his character: a human slave named Tak. During the Kessel mine heist, Tak can be seen when Chewbacca and his fellow wookie, Sagwa, part ways by pressing their foreheads together. Tak calls out to Sagwa by name, and shouts “This way!”
As noted by EW, Solo: The Official Guide offered some background on Tak and how he came to be a slave. Tak’s entree in the book describes him as a con artist who targeted the elderly while living on Coruscant. Tak’s downfall came when he tried to scam the Princess of Kessel. Even in the mines, Tak can’t stop swindling people and aliens, although the only benefit for him is a slightly easier work shift.
If there are any future Star Wars films set after Solo and before A New Hope, then it will probably be easier for Lucasfilm to justify Tak’s presence for Daniels’ cameos. Perhaps Tak could even be given a bigger role in the future.
