The Black Hole

Mise-en-scene
Dull & dim lighting, empty office - Tells audience that the time is way past office hours

Protagonist
The protagonist doesn't use any speech so we rely on his body language and actions to  narrate the story.
He stands completely still as if frozen looking extremely tired.
He sighs to emphasise his tiredness
He checks his watch which shows that he wants to leave

Message
Like many short films ' The Black Hole' follows the conventional method of portraying a message. This short is a metaphor for 'The force of Greed'. We can tell through use of sound effects and actions that the black hole is pulling the protagonist in like a magnet and that ultimately, his greed became his downfall.
