A man runs and jumps out of a 5th story glass window and using intestines as a rope, swings out till the line is tight, and swings back thru the 4th story glass window. This was done all in the same shot. The stunt was done using a reverse ratchet playing out slack as the stuntman ran thru and jumped out of the tempered glass and swung back thru the lower tempered glass window. No CGI was used for this stunt.
