Jonathan Groff as Marvin
For those who caught the original Off-Broadway staging of Spring Awakening, it was clear that Jonathan Groff, who gave an impassioned performance as questioning student Melchior, was destined for stardom. He was also an extremely moving Claude in the recent Public Theater revival of Hair. In fact, there is just something about Groff and his open-hearted delivery that makes audiences root for him, a quality necessary for the struggling Marvin, who is at the center of the Tony-winning Falsettos. He also possesses a pure, rangy tenor that would perfectly fit such Finn classics as "Father to Son" and "What More Can I Say?"

Andrew Rannells as Whizzer
A pretty boy with attitude. Who more fits that bill than the Tony-nominated Book of Mormon star Andrew Rannells, who plays the wise-cracking Elijah in the HBO hit "Girls"? Rannells, who recently proved his versatility as a heart-breaking Hedwig, would also bring heart and depth to Whizzer, who matures into a loving partner and mentor and friend to Marvin's son, Jason. His clear, soaring tenor would also break the heart in "You Gotta Die Sometime."

Leslie Kritzer as Trina
Those who have been fans of Leslie Kritzer have been waiting for the perfect role to showcase this comedically gifted actress' many talents. Although Kritzer never got the chance to bring her Fanny Brice to Broadway, the role of put-upon housewife Trina might be just the one to catapult her into a new level of fame. The Broadway belter would bring much comedy to "I'm Breaking Down" and great heart to "Holding to the Ground."

Josh Gad as Mendel
Chip Zien left such an indelible mark on the role of Mendel, it's hard to think of another actor portraying the neurotic psychiatrist. That is, until we thought of Josh Gad, the stage and screen star who hilariously originated the role of Elder Cunningham in the Tony-winning Book of Mormon. Gad is such a unique performer, one can hardly imagine the comedic antics he would employ as Marvin's shrink and Trina's lover.

Julia Murney as Dr. Charlotte
Julia Murney, who boasts a fierce Broadway belt, would no doubt deliver a show-stopping rendition of "Something Bad  Is Happening." And, like her work in Wild Party and Wicked, this Broadway favorite would also bring great dimension to the role of the well-intentioned doctor, one of the lesbians from next door.

Stephanie J. Block as Cordelia
In the past decade, Stephanie J. Block has displayed her range as an actress, starring opposite Hugh Jackman in The Boy from Oz, tap-dancing with great verve in Anything Goes and earning a Tony nomination for her dual roles in the acclaimed revival of The Mystery of Edwin Drood. Block also possesses one of the richest belts in the business, and we think she would be the perfect partner for Murney's Dr. Charlotte, playing the kosher caterer.
