As the summer heat continues – by UK standards, we should be expecting torrents of rain any second by this point – darkened cinemas are becoming increasingly less appealing. Particularly if they're not air-conditioned. So what better way to throw off the shackles of a roof than by taking in a film on the big screen in the open-air surroundings of London's Somerset House, where Film4 Summer Screen kicks off this week? Also on the agenda, we've got a Scottish screening for one of humanity's best worst films and the 80s invasion – already old news across the pond – finally comes to the UK.

5. Discover Gainsbourg

I haven't seen Joann Sfar's biopic of French maverick Serge Gainsbourg, but it opens across the UK today and promises an exciting look at the life of singer-songwriter and father of actor Charlotte. Today, The Curzon cinema in Soho is putting on a special screening of the film, preceded by an introduction from the director and followed by live performances of some of Gainsbourg's work. What better way to get an insight into an enigmatic soul? More news here.

4. Enter The Room

You may have heard about Tommy Wiseau's The Room. According to the retroactively penned synopsis, it's a black comedy, but the truth is it's one of the most painfully poorly conceived romantic dramas of all time. So poor, in fact, that it's also one of the funniest movies ever produced. Its comedy is all purely accidental, of course, and while those so-bad-they're-good movies are often just excruciating, this is a film which grabs you by the funny bone and doesn't let go until its unbelievably awful conclusion. It's not often been seen outside of the US, but it plays occasionally at London's Prince Charles cinema, where audience interaction with its pantomime brilliance is encouraged. This week, though, it's also playing up in Edinburgh at the Cameo, so folk north of the border can partake too. Click here for more.

3. Go to Summer Screen

Film4 Summer Screen, the open-air cinema programme which takes place at Somerset House every summer, has become an essential event on the UK film calendar, and this year promises to be better than ever. The event kicked off with a People's Premiere for Knight and Day on Thursday, and will screen films like Team America, Manhattan, Let the Right One In and Mulholland Drive over two weeks until the 8th August.

2. Meet The Karate Kid

The 80s are where it's at, apparently – at least according to this week's big-screen releases – with Karate Kid and A-Team reboots heading into cinemas. But there'll be no wax-on, wax-off in this update of The Karate Kid, though. For that matter, there's not even any Karate. The action is transposed to China, where nepotism's golden child, Jaden Smith, is the pint-sized mentee in search of schooling from Kung Fu master Jackie Chan. A predictable sequence of training montages and poor performance follows before the big finale, and like every film of its ilk – including the overrated original – its conclusion is surprise-free. But there's something endearing about it nonetheless, even if Jaden Smith's irritating smugness tends to have you siding with the bad guys.

1. Join The A-Team

Inception's all very well and good, but as we learn with this week's glut of big-screen actioners, if it's not based on an established universe – preferably from the 80s – it's not a summer blockbuster. Say hello to The A-Team, then, with its foursome of fearless souls we've either forgotten or are too young to remember in the first place. Director Joe Carnahan did the energetic Smokin' Aces, and brings his excitable style to this reboot, which is rather entertaining in spite of its inability to make much sense.
