The April 15, 2013 ,terror attack that occurred on the sidelines of the Boston Marathon has been etched into the memories of millions.

CBS Films’ “Patriots Day,” starring Mark Wahlberg, dramatizes the events of that infamous and deadly day, also takes viewers behind the scenes into the vast effort and series of quick decisions that led Boston to a city-wide lockdown and a tense manhunt for the brothers responsible for two pressure cooker bombs that killed three and injured hundreds.

This new trailer features added commentary from Wahlberg that doesn’t appear in the film and also flashes on several of the movie’s many dramatic scenes.

“Patriots Day” centers on Police Sergeant Tommy Saunders (Wahlberg) who found himself at the center of the tragedy and subsequent hunt for the perpetrators. Special Agent Richard Deslauriers is played by Kevin Bacon, Police Commissioner Ed Davis is portrayed by John Goodman, Sergeant Jeffrey Pugliese is played by J.K. Simmons, and nurse Carol Saunders is portrayed by Michelle Monaghan.

Directed by Peter Berg, the film has received glowing reviews, as reflected by its 93 percent score on Rotten Tomatoes. It offers a visceral, unflinching look at the sophisticated investigation and also the resilience of Boston citizens.

“Patriots Day” was also produced by Wahlberg, along with Scott Stuber, Hutch Parker, Dylan Clark, Stephen Levinson, Dorothy Aufiero and Michael Radutzky.

The movie opens in select cities on Wednesday and expands nationwide on Jan. 13.

15 Golden Globes Snubs and Surprises, From Martin Scorsese to Taraji P. Henson (Photos)

Here's who the HFPA embraced -- and dissed -- on Globes nomination morning
Martin Scorsese - Snub
The esteemed filmmaker was shut out of the Best Director category, which saw nods for the likes of Tom Ford ("Nocturnal Animals") and Mel Gibson ("Hacksaw Ridge").

"Silence" - Snub
Likewise, Scorsese's nearly three-hour epic about Jesuit priests in feudal Japan did not land Best Picture or acting noms for stars Andrew Garfield, Adam Driver and Liam Neeson.
Warner Bros.
Jonah Hill - Surprise
The little-seen Todd Philips comedy “War Dogs” landed Jonah Hill and Best Supporting Actor nomination (although our Awards guru Steve Pond did predict this).
Taraji P. Henson - Snub
The “Empire” queen and grounding force of Fox Searchlight’s “Hidden Figures” was given recognition for neither her TV day job (as she was last year, with a win) or her buzzy film turn this year.

“Empire” - Snub
Lee Daniels’ hip-hop saga was shut out of the Best Drama Series category after placing last year.
Fox
Colin Farrell - Surprise
“The Lobster” was a Cannes darling from 2015 that has eeked along on the charm of its alternate reality, where single people approaching the age of 40 must marry or be turned into animals. Farrell swooped in, taking several expected leading men out of the running.

Warren Beatty
Despite its low box office performance and lukewarm reception, "Rules Don't Apply" was expected to earn Beatty an acting nom. (Lily Collins did get a nomination for Best Actress - Musical or Comedy.)
Tom Hanks - Snub
The actor’s presumed nomination for “Sully” could’ve been by bounced by the inclusion of Viggo Mortensen and Joel Edgerton in the Drama Actor category.
Matthew McConaughey - Snub
The Weinstein Company drama “Gold” did not screen for voting groups and critics until late in the season, but McConaughey was expected to rate.
TWC
Simon Helberg - Surprise
As a very patient pianist opposite Meryl Streep and Hugh Grant in "Florence Foster Jenkins," Helberg emerged as an early contender -- and he made good with a surprise nomination for Best Supporting Actor Musical or Comedy.
Octavia Spencer - Surprise
Though her co-stars Taraji P. Henson and Janelle Monae have flashier roles in "Hidden Figures," this Academy Award winner came through with a Best Supporting Actress nom.
Robin Wright - Snub
The awards gods have forsaken the house that Underwood built, and snubbed the heart (or lack thereof) of "House of Cards" -- Robin Wright, in some of the finest work of her career -- as well as the entire series.
Netflix
Kevin Spacey - Snub
Same goes for her husband and worse half Frank Underwood.
"House of Cards" - Snub
And let's just go ahead and pour one out for the series as a whole, Netflix's first original breakthrough.

Netflix
Hailee Steinfeld - Surprise

The R-rated teen comedy has generated very little buzz, though there was talk about Woody Harrelson's performance as a high school principal. So Hailee Steinfeld's recognition as Best Actress - Musical or Comedy seemed to come out of nowhere.
