A 24 year-old man needs the helping hand of his ex-rival?s foul-mouthed womanizing ghost to overcome his impotence and get laid.

HI, Richiev!

Great feedback. It is confusing and needs clarification, as does the script. Your questions and suggestions definitely help. Thank you!

"A 24 year-old man"

This line doesn't tell us about the main character. You should say something like: A lonely librarian, an uptight business man, A reclusive neat-freak.
-----
"ex-rival?s foul-mouthed womanizing ghost"

This should be changed because it's a little confusing. (It could be read that his ex-rival had the same ghost haunting him)

"The ghost of his rival, a foul mouthed womanizer,"
-----
ex-rival

There is no context for this, was he a rival at work? Was he a rival for the love of a specific woman?
-----
"needs the helping hand" "to overcome his impotence"

Is his rival giving him handjobs??? If so, this is a great line, if not, I would change the line to avoid confusion :)

Interesting premise for a raunchy comedy, good luck with this!

I love the sound of this film. The logline feels very concise and to the point and made me chuckle.
