Matt Wolf at The International Herald Tribune prefers Russell Beale to Alex in "The Alchemist", and isn't that keen:
"But painful though it is say, the show turns out to be a triumph for Russell Beale rather more than it is for Jennings, who perhaps has the disadvantage of not having acted Jonson's tricky language on the imposing Olivier stage."
"In T-shirt and suspenders one minute, Russell Beale's Face is all slicked-back officiousness the next, at another point appearing in goggles only to be cradled by Jennings's Subtle (note the character names) as if he were an untamed dog. Jennings's accents - a cringemaking American one included - somewhat hamper a play about artifice that, paradoxically, has to look easefully managed. Betray the effort involved, as is the case here, and you have a momentous pairing that isn't quite the expected exercise in mirth."

And more reviews for "The Queen":
"Along with the imperiously indignant Cromwell, the supporting cast is brilliantly rounded out by Alex Jennings as a skittish Prince Charles, Helen McCrory as Blair’s wily wife, Roger Allam as the queen’s diligent aide and Sylvia Syms as the queen mother, who is often hilarious in her regal dismissiveness of the outside world." (David Germain)
But the film also has some wonderful performances from Alex Jennings (who's Prince Charles is surprisingly weak and sympathetic -- who knew the man was fearing for his life that week?) (Erik Davis)
Andrew Stuttaford in the New York Sun describes Alex's performances as "splendidly twitchy".

USA today doesn't have a review but a different story:
Prince's pals perturbed by portrayal
The Queen screenwriter Peter Morgan says friends of Prince Charles are not pleased with his portrayal in the movie. In it, Charles (Alex Jennings) is portrayed as trying to please his mother, Queen Elizabeth (Helen Mirren), after the death of his ex-wife, Diana, while working behind the scenes with Prime Minister Tony Blair to urge the queen to publicly express her grief. Queen opens the New York Film Festival Friday and expands in October.
