Just look at the way the light glints off that heartbeat sensor...

Step aside, Academy Award winners, there's something more important happening on TV tonight: Samsung's aired their first commercial for the upcoming Galaxy S5 smartphone. The S5 might be several weeks out still, but that doesn't mean the marketing blitz can't get underway. After all, there's a 5.1-inch HD screen and heartbeat sensor to hype.

Apart from the 30-second dramatic teaser, Samsung's also put up a 90-second "Amazing Things Happen" video that covers everything that Samsung offers with a screen, and apparently "You need to see this." Well, you can see it after the break.

Update: And later on in the evening, an ad for the Tizen-powered Samsung Gear 2, in much the same vein as the Galaxy S5 ad. Check it after the break.
