How does a Tony winner try to score a place in the Guinness World Records? For Jersey Boys star Hoff, 38, it's by voicing an unprecedented 241 characters (sorry, Harry Potter reader/current record holder Jim Dale!) for the audiobook Tell Me How You Love the Picture. Here, Hoff explains how he morphed into some of those A-listers for producer Edward S. Feldman's (Witness) account of five decades in movies.

JACK LEMMON
''That was a tough one. He has a higher voice than I do. And the way he talks is kind of manic and nasal. So I pitched it up a bit higher.''

JIM CARREY
''From what I know of him, he's soft-spoken; when he's not on, he's off. So I did more of Jim Carrey's underbelly, as opposed to his manic side.''

HARRISON FORD
''Harrison is very dry and shy in his personal life, so the take I took on him was very matter-of-fact. I didn't try too hard with that one.''

EDDIE MURPHY
''Eddie called Feldman 'the Man.' If they were ready for him on the set [1986's The Golden Child], he'd say, 'Is the Man ready for me? Then I'm ready.'''

JOAN CRAWFORD
''She's so over everything all the time. You just raise your eyebrows and draw up your voice a little bit and you nail Joan Crawford.''
