Question

What are the similarities and differences in acting for film and theater productions?

Answer 1

Theater is harder bc you have to do it over and over again and you can't just "cut" and reshoot

Answer 2

Both require lots of acting and talent.  Some could argue that theater requires more of a devotion and more of a portrayal of emotion.  Many theater productions are the works of world renown composers that are thought highly of.  Hope this helps and gets you started.
