The supporting cast is peppered with Apatow regulars such as Bill Hader as Peter's disapproving stepbrother, Jonah Hill as a weird waiter, and Paul Rudd as a brain-fried surf instructor. This trio, along with pretty much everyone else who appears onscreen, do a wonderful job of helping to propel this story forward and give it that surprising depth. Oh yes, I cannot forget Jack McBrayer (30 Rock) with his funny turn as a religiously minded newlywed on his honeymoon who quickly discovers that he has a lot to learn.

Jason Segel, in addition to starring, makes his screenwriting debut with Forgetting Sarah Marshall. It may be his first credited piece, and I am sure that Judd Apatow helped guide him; he has crafted a fine script that is injected with a healthy dose of heart while never forgetting that it is a comedy. The dialogue is smart, witty, and feels very real. Now, the situation may not exactly be realistic, but the way it flows it has a naturalistic feel that bolsters its believability.

At the helm is Nicholas Stoller, also making his debut, albeit as a director (previously penning Fun with Dick and Jane). His directorial style is laid back, letting the actors tell the story. Despite the lack of flash, the directing is solid.

Bottom line. This is one of the best films I have seen so far this year, and easily the best comedy. It offers big laughs and outrageous situations while simultaneously being undeniably sweet and utterly human. The combination serves the film well. It had me smiling as I left the theater knowing I saw something special.

Highly Recommended.
