An innocent is corrupted in South African director Neill's Blomkamp's third feature (co-written with his wife Terri Tatchell), but the kid in question is far from what you'd expect. Set in the near future, it focuses on a reprogrammed police robot with the consciousness, sensitivity and suggestibility of a child - a lovably tatty piece of tech who has been literally labelled a reject, and who sports bunny ears, graffiti and gangster bling.

Techland's previous first-person zombie game was Dead Island. This swaps its beach resort location for a nondescript south American city, and its supercharged, cobbled-together weaponry for parkour-style run-jump-climb agility. One of these swaps is good news, the other not so much.

Crash-landing in the zombie-infested city of Harran, your undercover government operative has to ingratiate himself with the locals, trying to survive holed up in a tower block. How he does that is largely by going and fetching things for them from all over.

Against the background of the spectacular scenery of Patagonia, Argentinian director Lucia Puenzo creates a tight, subtly unnerving thriller in her third film Wakolda. Its American release title “The German Doctor” reveals its subject more immediately, which is the time spent by Nazi physician Josef Mengele (Alex Brendemuhl) in Latin America after his flight from Europe.

Gary Lineker has been honing his marketing schtick for several decades now, selling us a spud-based product that promises to make us feel great, only to fill us with self-loathing as soon as it’s finished. Yes, the England football team, seemingly made of potato, slickly packaged, but ultimately unsatisfying and undoubtedly bad for your health. (The crisps, I hear, are much healthier than they used to be.)

If Crystal Fairy is about "the birth of compassion in someone’s life”, as director Sebastián Silva explained when it premiered at Sundance last year, then Magic Magic (which he shot at the same time) can be seen as a companion piece of sorts. It’s not too far a reach to assume Silva is testing his audience with this disorientating and incredibly taut look at mental illness.

It’s strange that probably most of the best-known Brazilian artists here are over 60 and from one state, Bahia - those being Caetano Veloso, Gilberto Gil, Maria Bethania and Tom Zé. Brazil is the size of Europe, though, and of course there are younger generations from other states. One of the leading new voices is Karol Conka, whose Brazilian electronica is as fresh as anything you are likely to hear this year.

Crystal Fairy (or to give it its full, original name Crystal Fairy & the Magical Cactus and 2012) is an endearing curio from odd-couple director and star Sebastián Silva and Michael Cera, who have teamed up for a double-bill of projects: the other one is the psychological thriller Magic Magic, currently scheduled for an April release.

Gloria is 58. Divorced 12 years earlier, she’s intent on living life. Her two children are grown up, she works in a characterless office and is open to almost anything. She’ll try cannabis, attends a class where instruction is given on releasing laughter and tackles yoga for the first time. Beyond keeping in touch with her son and daughter, her greatest efforts are directed towards her nightlife. On her own, Gloria goes to ballrooms, bars and nightclubs where she hopes to make a connection. Then, one evening, she encounters Rodolfo. His opening line is “are you always this happy?”

Anyone who saw or attended this year’s Last Night of the Proms will know that Marin Alsop is a born communicator with a wry sense of humour. Another of those youthful crowds The Rest is Noise festival keeps attracting gave her a hero’s welcome last night, and she responded with easy compering.

Respect and dignity, intolerance and hatred: the poles were set far apart in Stephen Fry: Out There. It’s good to have Fry the thoughtful presenter back – it’s been a long time since his The Secret Life of the Manic Depressive – on a subject close to his heart, how gay people are faring in various parts of the world. This first episode took us to Uganda and Los Angeles, while part two on Wednesday drops in on Brazil, Russia and India.
