With Edge of Tomorrow now available to stream, it's a great time to revisit the making of the film, and just how many practical effects were used. Watching the video above, it's impressive to see so many real effects and explosions going on around the actors. While more and more effects are being done with computer graphics, there has been a bit of backlash to fake-looking CGI, and a number of filmmakers (like Christopher Nolan) have bucked the trend and have attempted to get as much in-camera as possible (J.J. Abrams is also doing this on the new Star Wars film).
It takes a lot of skill and professionalism to make sure these practical effects are safe, but getting more in-camera means actors have a lot more tangible real-life objects to react to (and hopefully better performances as a result). This BTS video from the movie Oblivion shows a great example of using practical effects to help both the production and the actors get a more realistic result (and Tom Cruise just happened to start in both of these films):
