Death has not any trouble killing anyone, but an old man hides his scythe and makes Death go back to his house to kill him, in that time he prepares a surprise for Death.

The logline does not flow off the tongue. The repeated Death, Death, Death is unwieldy. You don't need to tell us that Death has not had any trouble killing anyone. Be as concise as possible: Something like: "When a tricky old man hides Death's scythe, the source of his power, Death must find the man and retrieve it. But the old man has a surprise for him..." I'm not sure this tells us enough about the script, but it's easier to read.

Thanks Nir, I have prepared the script for this short film, and I would love if you could give me some advice, You I could contact you in a more personal way to tell you about it?

Thanks Nir, I just read that story and made me think a lot. Karel it is up for a short film.

For me the MC all the story is Death and the man as an AN.

Thanks a lot for your response! =)
