In the beginning VS AT the beginning

[hela]

Dear friends,

Would you please tell me when should I use "IN the beginning" or "AT the beginning" ?

Thank you in advance,
Hela

At the beginning- when something starts
In the beginning- suggest that the position changed- In the beginning, I found it hard to get on with him (Implies that we get on now). You could use 'at' in this sentence without really losing the meaning, but I wouldn't use 'in the beginning of the film' to describe the first scene.
