Looking for a similar movie to Berbarian Sound Studio

Hi guys!
I am new here and desperate about finding a movie that is alike to Barbarian Sound Studio. It is kind of urgent haha and I am looking for similar one for quite a long time but unsuccessfully. Can anybody help?
Thanks!

One of the reviews on IMDB compares it to Amer (2009) , I have never seen either of these movies but thought I'd throw it out their anyways.

This is a weird coincidence because sometime in the last year when I was watching a movie I remember thinking " Boy, this reminds me so much of Berberian Sound Studio!" Unfortunately, I can't remember now what it was, but if it comes to me, I will post the title.

Thank you guys so much you have no idea at all how much you helped me, i was so close to having a nerve breakdown hah.
sleightofhand, please if you remember the title, please tell me it would be REALLY great.
P.S.
If you know any British one similar to Barbarian Sound Studio that would be great also.
THANKS!
