Many tales have been told of the underdog taking on a deadly foe in battle. Our hero is usually brave, fearless and looks quite dashing in doublet and hoes. However, it’s safe to say that Danny McBride’s take on this historical protagonist walks a very different path.

All is seemingly well in the kingdom of the King (Charles Dance); his eldest son Prince Fabious (James Franco) has just returned from a successful quest, where upon he has rescued the fair maiden Belladonna (Zooey Deschanel). Not only that but his head has fallen over his heels in love with her; so much so that they are to wed immediately.

Everyone finds this news fantastic; everyone except the Prince’s brother that is, Prince Thadeous (Danny McBride). Thadeous is everything his good brother is not; selfish, spineless, rude and arrogant. The fact that his brother will one day be king irks him enough, but it’s compounded by the fact that he’s now got himself a hot bride. Although Fabious requests his brother to be his best man, Thadeous goes off in a huff and avoids the event.

Luckily for him, he doesn’t witness the arrival of the evil warlock Leezar (Justin Theroux), who gate crashes the wedding; Fabious battles with him but finds Leezar invulnerable to the thrust of his mortal sword. Leezar once again nabs Belladonna and makes off with her to his realm.

Heartbroken, Fabious decides he must set off on yet another quest to rescue his love. The king however, decides that he must not go alone, and that his lazy brother must accompany him and hopefully become the man he so wants him to become. Although not entirely keen on the whole quest thing, Thadeus joins the rescue party, along with his faithful servant Courtney (Rasmus Hardiker).

The road ahead is not a simple one however, for the group must encounter much danger before they can take on Lezaar; for one, they will need the Blade of the Unicorn which is no easy feat in itself. And so begins Thadeus’ first ever quest – with the odd sub quest along the way...

Something has to be said for the city's latest green transport initiative, talk about forward thinking!

At first glance, Your Highness feels like a sweet take on the fairytale theme, not unlike 1987’s charming The Princess Bride. It’s not long however, before you’re aware that unlike that classic, this film has far more adult themes. In fact it can be best described as the bastard child of The Princess Bride and a Monty Python film.

What director David Gordon Green (Pineapple Express) has done essentially has transposed your modern day teen romp into ye olden days, with a little Carry On thrown in for good measure. The only difference however is the use of the language; when Thadeus and the rest of the characters swear for instance, it’s with a very modern vibe.

Much of this is down to Danny McBride. McBride is very much an acquired taste; fans of his show Eastbound & Down will take to his character immediately. This is due to the fact that despite a dodgy English accent (which to be fair, the entire cast suffer from; it sounds as if they were taught it by someone with a very thick German accent) Thadeus is a medieval Kenny Powers. McBride’s performances are always lo-fi, so you either get it, or you don’t.

And although McBride pretty much steals the show, he’s supported by some great actors, not normally known for their comedic abilities; Franco appears to revel in his performance as Prince Fabious, and it’s great to see Portman let her hair down and not take herself too seriously. British thespians Toby Jones and Damian Lewis also have a good time, as does Hardiker, who appears to be evolving his usual slacker role (as seen in Jack Dee’s TV show Lead Balloon).

It’s not the most sophisticated comedy you’ll ever see, but if you’re partial to the odd knob gag, laced with drug humour, then Your Highness could be right up your thoroughfare yonder. Bawdy, silly fun.
