Mr Birling character advice

Give advice to the actor playing Mr Birling on how he should present the character to an audience?
In this essay I am going to discuss Mr. Birling character in depth and advise the actor who plays him on how he should be presented.
Mr Birling is a ‘heavy looking, rather portentous man in his middle fifties’ who is head of the family.

Also since Mr. Birling made his own money he has come for a poor background and this can be seen when his wife reprimands him for praising the cook, therefore whilst he is powerful he also lacks education and manners.
During their dinner Mr Birling begins to make a speech and the actor should stand so to captivate and hold everyone’s attention. Mr Birling considers himself to be a ‘hard-headed business man’ and in his speech, a key moment in the play he states a list of wrong predictions.

This would lead the in questioning his judgement. During his speech Mr. Birling refers to his kids as ‘youngsters’ and informs them they have nothing to worry of. At this point I think the actor should appear
