Five months after it became the first major streaming hit of 2021, Lupin will return Friday with fans desperate to see how Omar Sy's gentleman-burglar escapes the latest cliffhanger. 

Netflix delivered only the first five episodes of the show in January, inspired by the cat-and-mouse novels of Maurice Leblanc from the early 20th century, because the pandemic interrupted filming in 2020. 

Sy plays Assane Diop, a fan of the novels who uses the character of Lupin as he seeks vengeance for his wrongly-accused father.

The combination of a charismatic lead, Parisian backdrops and an undercurrent of race relations made it the first bona fide made-in-France hit for Netflix, which is investing heavily in the country.

But despite the winning ingredients, Sy himself seemed rather perplexed when asked why it was so popular.

"I really don't know!" he told reporters at a Netflix round-table, laughing. 

"When something like that happens the thing is just to embrace it and don't try to understand. It's just beautiful, I'm very happy and thrilled."

Writer George Kay, who also helped pen recent TV hits Criminal and Killing Eve, said the season takes a tense turn in the second half.  

Assane finds himself "in a conflicted situation: Do I keep pushing to get revenge for my father or do I focus on being a good dad," he said at the round-table. 

But Kay, who worked alongside French writer Francois Uzan, said Lupin remained a family-friendly show and "the central thing is to make it as fun as possible."

Paris retains its starring role in the new season, with the Musee d'Orsay, catacombs and Chatelet Theatre making for sumptuous backdrops to the action.

Dubbed into some 15 languages, and subtitled into 30, Lupin topped the Netflix charts in a dozen countries in January, including the first time a French show had done so in the US.

The company said 76 million households watched the first installment in the first 28 days after its release, beating its main non-anglophone rival, the Spanish crime drama La Casa de Papel (which clocked 65 million household views for its fourth series).

It was a much-needed boost for Netflix after its first foray into the French market, 2016's Marseille, was panned by critics. 

The streaming giant had a rocky start to its relations in France, where it has sometimes been viewed as a threat to the country's beloved cinemas. 

But having opened a swanky new Paris headquarters in 2021, Netflix has made significant in-roads, partnering with creative associations and schools, and announcing a major production boost for 2021, with 27 films, series and documentaries in the pipeline. 

Lupin has also been a boost for French bookshops, with new editions of Maurice Leblanc's classics racking up more than 100,000 sales since January, according to publisher Hachette.
