We have to hand it to James Franco – he did warn us right from the start.  He did his best to lower our expectations.  “I did one other talk show before this [that scintillating talkmeister] Tony Danza…I’m really nervous.”  But even that failed to prepare us for his scattered performance during an appearance to promote his new movie, Pineapple Express.

The ingredients were there.  He had a pocketful of great stories:

•    His grandmother named her dog Dave and decided to teach it Stupid Pet Tricks.
•    His parents hated the idea of him being an actor – now the whole family is in show business
•    In his struggling actor days, he worked at McDonalds and used to pick up girls by doing a fake Italian accents

All terrific stuff, but here was the BIG mistake: these stories were woefully under-rehearsed.  Even the best actors (and James Franco is a real pro) often fail to realize being a talk show guest is about performing.  It takes prep, people!  It’s hard work being naturally you, and just dredging up a few stories (however cute or funny) doesn’t cut it unless you rehearse.  And don’t depend on the show’s producers to get you up to speed – this is a task that should be tackled well in advance.

It’s all so hard on TGW because Franco is just so damn likeable!  He has the potential to be a great guest, once he focuses his anecdotes and gets some feedback (are you listening, managers, agents and publicists?) to help him gauge how his stories work.  We’ll certainly watch for him on his next outing.

When Seth Rogen edged out onto The Tonight Show set, he looked less than a sure thing.  Sure, he had a nice suit, fashionably loose tie, and a fashionable-three-years-ago five-day beard.  But he looked painfully uncomfortable, rarely making eye contact and sitting tensely.  What a wonderful surprise to see him turn in a textbook performance as a great guest.

He first blew our expectations out of the water when Jay displayed a cover of GQ with Rogen front and center.  Pointing out his modified-fro curls, Jay asked, “Is that your hair?”  “Yes,” Rogen replied. “And if you’re wondering, the carpet matches the drapes.”  The audience fell apart!  Rogen milked his doofus persona and kept Jay in stitches throughout his segment.   He had done his homework: bringing out a picture of Jay in jeans and denim shirt (his favorite outfit), Rogen referenced his Northern roots by noting “We call this a Canadian tuxedo.”

The comedy centered on Rogen’s underachiever past, showing a clip from Dawson’s Creek that revealed the stoner character he plays in Pineapple Express (which he was promoting) has deep roots.  Jay even bounced jokes off of Rogen’s parents – in the audience – throughout the segment.

So why did Rogen succeed when he broke so many standard guest appearance rules?  He stuck close to the most important rule: reveal something about your true self that the audience and the host can relate to.  Play to your entertainment strength.  And he did this masterfully.
