THE GREEN HORNET STRIKES AGAIN (1941) -- colorized

The Green Hornet Strikes Again! is a 1941 Universal black-and-white 15 chapter movie serial based on The Green Hornet radio series by George W. Trendle and Fran Striker. It is a superhero-themed story about the eponymous superhero, the Green Hornet. It is a sequel to Universal's earlier serial The Green Hornet (1940). This was the 117th serial (the 49th with sound) of the 137 that Universal produced. The plot involves racketeering and is unusual for a movie serial by having mostly stand-alone chapters instead of each running into the next; this was also the case for Universal's first Green Hornet serial
Plot

Wealthy publisher Britt Reid and his trusted Korean valet and sidekick disguise themselves as the crime fighting vigilantes, The Green Hornet and Kato. Over the course of 15 chapters, they battle the growing power of ruthless crime lord "Boss" Crogan and his varied rackets and henchmen across the city. Unknown to them, Crogan also has strong ties to foreign powers unfriendly to the United States.
