As Buck Howard (John Malkovich) explains in Sean McGinly's funny valentine to the talk show mainstays of yesteryear, he's a mentalist, not a magician. Unlike the brooding protagonists of "The Illusionist" and "The Prestige", Howard doesn't do Harry Houdini-style tricks. Rather, he reads minds, finds hidden objects, and performs other feats that eschew props and assistants. Back in the day, Howard appeared on "The Tonight Show" 61 times (McGinly based his character on The Amazing Kreskin), but his best years appear to be behind him when he takes on law-school dropout Troy (a low-key Colin Hanks) as his road manager. From the start, Troy finds his temperamental employer fascinating and frustrating in equal measure. Desperate to get back in the limelight, Howard decides to hypnotize several hundred audience members at once. Along with a sassy press agent (Emily Blunt) and two over-enthusiastic venue managers (Steve Zahn and Debra Monk), Troy works with Howard to make it happen. To his surprise, things go both better and worse than expected, and everything changes for the unlikely pair. Produced by Tom Hanks's Playtone banner and featuring the two-time Oscar winner as Toby's disapproving father, "The Great Buck Howard" follows the rise, fall, and rise template of many Hanks productions (see "That Thing You Do!"), but McGinly handles a large cast with ease, the laughs are plentiful, the cameos--John Stewart, Conan O’Brien, George Takei, etc.--are a treat, and the unpredictable Malkovich gives his most nuanced performance since, well, "Being John Malkovich".
