Tom Brady threw four touchdown passes -- two each to Brandon Llyod and Rob Gronkowski -- as the Patriots cruised to a 45-7 rout of the Rams at Wembley Stadium in London.
The Patriots (5-3) scored touchdowns on their first five possessions before having to settle for a field goal on their sixth drive.
For the Rams (3-5), the game showed they have a long way to go offensively to contend with the NFL's heavyweights.
The London fans had to be impressed with the American football exhibit.
Brady was 23 for 35 for 304 yards, Gronkowski had 146 yards on eight catches and Stevan Ridley rushed 15 times for 127 yards and a score.
Rams quarterback Sam Bradford was 23 of 31 for 205 yards. He was intercepted once.
The Rams' young and improving offense marched down the field quickly on the game's opening drive and grabbed a 7-0 lead when the rising star fired a 50-yard TD strike to Chris Givens just 2:25 into the game, easily beating defensive back Tavon Wilson deep down the middle.
It was similar to when another young quarterback, Seattle's Russell Wilson, beat New England's beleaguered secondary on a game-winner a few weeks back.
But that's where the young gunslinger was clearly outshined by New England's trophy passer.
Brady connected on his first eight passes for 119 yards and led the Patriots to TD drives the only four times his team had the ball in the opening half, helping New England open a 28-7 edge at intermission.
On the first drive, Brady went 4 for 4 and his touchdown pass gave him a scoring pass in a 40th straight game, connecting with a wide-open Lloyd in the right corner to tie the game at 7-7.
The Patriots took a 14-7 edge when Shane Vereen scored on a 4th-and-goal from the 1, bursting through the right side of the line. The score was set up by a nifty over the shoulder catch by Gronkowski, who hauled it in and was touched on the ground just short of the goal line.
Brady, didn't stop there. Not even close.
On the next possession, New England went 78 yards in nine plays, with Brady capping it with a 9-yard scoring strike to Gronkowski, who celebrated by marching like one of the Queen's guards outside Buckingham Palace before one of his patient spikes.
Just before the half, Rams' holder John Hakker mishandled a snap on an attempted 54-yard field goal and New England took over near midfield.
Yep, Brady then did it again. This time, it was 56 yards in nine plays. Steven Ridley topped it off with a 1-yard run. The play was set by Brady Fetcher's interference on Deion Branch in the end zone -- the safety's third interference of the half.
They opened the second half the same way -- easily marching down the field before Brady hit Lloyd with a 9-yard TD pass.
The Patriots led 38-7 after three quarters. Brady hit Gronkowski with a 14-yard scoring toss early in the fourth, setting off another 'Gronk Dance' under the stars at Wembley.
Midway into the second quarter, the Rams had a big scare when Patriots linebacker Dont'a Hightower drove Bradford into the ground, dropping him on his left shoulder. Bradford, who has a history of injuries, was slow to get up. The Rams called a timeout and he returned to the game without missing a play.
