Opening Scene - Taxi Driver

• heavy music - gives the audience a hint that the main character may be a villain
• scene is heavily focussed on dialogue - shows us a lot about the character
• zoom in on face - makes the audience more familiar and become closer to the character
• high angle on the interviewer makes him seem more vulnerable and inferior compared to the low angle on DeNiro making him seem more powerful 
• diegetic sounds of the office make it seem like a busier setting - more interesting for the audience to watch and gives a clear idea of the type of office he's in
• point of view (low angle) looking up to DeNiro - gives the audience an idea of how others view him
• conversation is also mainly focussed on DeNiro, clearly showing he is the main point of interest for the audience
