-Comment: At least 2 actors as Alexei/Tsarevich a young boy, I think Oliver John Lock in a medium blue sailor suit with a white collar and the older boy/teen played by Oskar Mowdy in a white sailor suit and dark blue collar. Also in other clothes.

I haven't seen the complete series, but I assumed rather few sailor suit scenes.

I also found 2 other Rasputin/Alexei movies for my list, checked the full movies, but no real sailor suit scenes there:

Anastasia: Once Upon a Time

Tsarevich Aleksey (1996) Russian title: Царевич Алексей
