Arsenic and Rewriting

Have I mentioned I'm playing Officer Klein in Arsenic and Old Lace? I have read that the author originally intended the play as a grim study, but that some Broadway producers convinced him to turn it into a comedy.

It's very well structured as a comedy. I wonder what it looked like as a drama.

It's certainly got all the trauma
you need for a drama.

Could it be that all the laughter
was added after?
