Unfortunately I have no idea which Egyptian movie this short clip is from. Any information would be greatly appreciated.
Nabaweya Mustafa is the dancer in this scene from the 1947 Egyptian film ‘Ana albi dalili’ (My Heart is My Guide قلبي دليلي). The film starred Anwar Wajdi, the man in the overalls and Leila Mourad who’s the girl locked in the basement with the villain of the film, Stefan Rosti. The singer is Mahmoud Abdel Aziz aka Abdel Aziz Mahmoud (عبدالعزيز محمود).
Trivia 1: In the film there’s a scene set at a masked ball where three masked thieves (who are disguised as three masked thieves) mix with the guests. The thieves are played by well known Egyptian screen actors Abdelmonem Ismail and Abdel Hamid Zaki along with a very young Farid Shawki.
Trivia 2: The toothless guy who features in the clip is a member of the gang of kidnappers and is played by Riad al Kosabgy (رياض القصبجي).
Mohamed Fawzi and Leyla Fawzi sing in the finale of the 1959 film ‘Layla, Bint al Shati’ (Layla, Girl from the Shore ليلى بنت الشاطئ) which also starred Wedad Hamdi who’s in the audience.
If you’re not into singing then jump to 4:18 for a trio of dancers.
