James Cameron-Wilson says that box iffice is down 52% although A Minecraft Movie has powered ahead to a £31m take. #2 The Amateur has Rami Malek as a desk-bound CIA guy who wants to get trained up for revenge. But it's ludicrous and underlit and very disappointing. #6 the unheralded Drop is a thriller with Meghann Fahy on a date that goes badly wrong. Think of Speed in a restaurant. James was completely gripped by the ingenious plot. He also admires #16 Mr. Burton with Toby Jones the teacher who inspired Richard Burton to at. It's the sort of little film that Britain does so well and deserves an audience. Simon recommends the new Eureka double-disc silent Laurel & Hardy restoration.

Steve Caplin is desperate to buy the Kawasaki robot horse which can do everything a horse can but is powered by hydrogen. Sadly it's still only a beautifully-realised CGI concept. But there's a renewable energy motorbike with a roof covered with solar panels and a wind turbine. Or a WalkCar the size of a laptop. Or even an electric skateboard that goes at 45mph. Ford have patented a gear stick for electric cars, for drivers that miss them. There's an aircraft that can land itself, a weird-looking robot chess player, a trial postbox with a barcode reader to scan parcels, a Sardinian beach you'll need an app to visit and a tip on how to hear better in noisy rooms without spending a penny – though it ought to mean domino players can hear brilliantly.

FInlay Mathers of Edison Group discusses Rolls-Royce which, under new management, met all its turnaround targets two years early and confounded investors' attitudes towards its business, comprising civil aviation, aerospace and power systems. The shares are above the industry average but it's a fantastic business whose air business has a "power by the hour" model linking it to the upturn in global air travel, while its defence order book is up by 89%. The future may be bumpy, but the business is very sound.

Stockmarkets are so chaotic in the wake of Trump's various announcements that we're delighted to replay a short summary clip called 'Superinvestors' from August 2017. In a partnership with publishers Harriman House, Share Radio produced its first audiobook 'Superinvestors', written by Matthew Partridge and read by some of Share Radio's best known presenters. 'Superinvestors' lays bare the investing secrets of legendary investors - from early 20th-century figures such as Benjamin Graham and John Maynard Keynes, through to more modern names such as Anthony Bolton and Warren Buffett — download it at https://www.harriman-house.com/superinvestors . If wisdom improves with age, this might be useful today ..

This week James Cameron-Wilson is joined by Chad Kennerk, our occasional American correspondent fresh from his trip to CinemaCon in Vegas. James is thrilled to see that the UK box-office has leaped a phenomenal 168.7% from the previous weekend, thanks to the video game adaptation 'A Minecraft Movie' with Jason Momoa and Jack Black. At #4 is 'Death of a Unicorn', a farcical horror comic that is inept on almost every level, save for the presence of Jenna Ortega. However, at #7 is the Oscar-winning animated feature 'Flow', which James claims is the best film of the year so far, being an enthralling, mystical, frequently quite funny, wondrous, haunting and even a pulse-accelerating experience. He was less happy with 'The Electric State' on Netflix, a $320 retro-futuristic mess with Chris Pratt and Mollie Bobby Brown which he describes as being overblown, heavy-handed and visually cluttered.

Chloe Won Yung Shin of Edison Group discusses Michelmarch Bricks' recent results. It makes 122m bricks and pavers a year, has a strong balance sheet and should benefit from the UK's structural shortage of housing. On a discount to its peers, it has 7% of the market with further upside potential. Andy Murphy, director of content for Industrials at Edison is intrigued by Smiths News. A regional distributor of newspapers and magazines, it is handling a declining market well, stripping costs back and diversifying by collecting dry waste from those shops it delivers to. It's a cash generative business that has long been ignored and undervalued and yields twice its PE.

James Cameron-Wilson reports that the box office is down 14%. #2 is A Working Man, a violent, noisy and hugely unrealistic shoot-em-up with Jason Statham scything through Russian baddies as he tries to rescue his boss's daughter. It's like a poor knockoff of Taken. James hugely recommended Novocaine at #5 with Jack Quaid a man incapable of feeling pain. Although occasionally violent there are a lot of laughs and some superb twists (and more plausible fights) in a beautifully-plotted film. He also recommends – for those with strong stomachs – the 5-time Oscar-nominated Demi Moore horror movie The Substance. It's now out on disc and is a must for horror fans.

Steve Caplin is impressed by a Chinese car with predictive suspension that remains level going over bumps and can even travel on three wheels. China also launches pilotless air taxis. There's a personal VTOL and a zero-emission hydrogen-electric jet. The AI Therabot can lower depression by 51%. A top accounting firm is having to train its GenZ workers how to use telephones. AI can improve your prospects for internet dating. And the University of San Diego has developed a pneumatic 3D-printed six-legged soft-body robot.

Professor Tim Evans of Middlesex University says that people should not look at Trump's tariffs in isolation. They are only part of his strategy. The press ignored his remarks on the US needing legal immigration, supply-side reforms and a new tax regime to unleash the country's potential. There are risks but, if he succeeds, we could be in a different world. While the UK government considers tinkering with ISAs, Tim says that savings are underestimated and that you can't have capitalism without capital and we need more financial education. He also cheers the fact that the UK will have its first rocket launch this year, enabling us to participate in the vast and growing satellite market.
