Drew:

Congratulations on bravery to start a theatre company and your success with your first production.

I like your choices. 

For comedies, check out some of Alan Ayckbourn's earlier plays, specifically one of the three in "The Norman Conquests."  Also, Noel Coward's "Private Lives" and "Blythe Spirit."

Suggested second production (following your all girl version of the "Odd Couple") is a wonderful play rarely done these days and that is "The Hasty Heart."  All male but for female nurse.  "Separate Tables" is a great play to do.

"The Glass Menagerie" (excellent classic) and "Little Shop of Horrors" (fun musical) are good choices, to give a variety to your presentations that include your premiere production.  May I suggest one original play per year, running it for your third production?  I have found that audiences like this.  You can put out a call  on the Internet for new works for your theatre company.  This site, as well as The Playwrights' Noticeboard, EnVant Playwrights, and Rosa/Ashley Writers' Forum.

Off hand, some other dramas/comedies you might consider:

"And Then There Were None" (saw this in London and it is still great)

"Brigadoon"

"The Chalk Garden"

"Divorce Sale" (comedy by me)

"The Seven-Year Itch" (wonderfully silly)

"The Great Sebastians" (always works well in community theatre)

"Teahouse of the August Moon" (award winner)

"Crow" (powerful Australian play)

"Goodbye, My Fancy" (great role for actress)

"Susan and God" (ditto)

"Finian's Rainbow" (musical)

"Ring Around the Moon"

"Prelude to a Kiss"

You might want to go online and check out abstracts on plays published through Currency Press, PlayPro, and ScriptCircle. 

The theatre department at the university in the community where I live oftentimes pick a theme to thread together their four productions per year.  You might want to try this.  It is a fun thing to do.  For example, where there is a combination of three:  "Three Sisters," "Macbeth" (three witches), "Sorrento Hotel" (three sisters), and "Living Together" (two sisters and a brother).  Or you could do plays where there are trials.  For example, "The Merchant of Venice," "Witness for the Prosecution," "The Caine Mutiny," and "Trial and Error," a very early comedy by John Mortimer.  (If you're going for one musical per year, there are several with trial scenes.  For example, "Chicago" and "Lady in the Dark." 

I'm afraid I have gotten carried away. Sorry.

Continued G'd luck to you.
