The flirtation between theater and television has turned serious in recent seasons. Small-screen favorites Stranger Things and Smash were adapted for Broadway, and Schmigadoon! is on tap for next spring. Meanwhile, Off-Broadway satires of The Office and Friends have settled into long runs. Now add to the lineup Not Ready for Prime Time, a new play by Erik J. Rodriguez and Charles A. Sothers. Neither an adaptation nor a parody, this likable, free-flowing piece is more a biographical comedy, albeit an unauthorized one.
