Justin Timberlake's acting resume is about to hit Rocket Man status.

Elton John recently singled out Timberlake as the top choice to take the lead in an upcoming biopic.

I've got a wish list of people. No. 1 on my wish list is Justin Timberlake, because he played me before in a David LaChapelle video of 'Rocket Man' and was superb, John told the LA Times.

The 64-year-old music legend also revealed that the biopic already has a director, with a script by Lee Hall (Billy Elliot).

While Timberlake, 30, has yet to comment on the offer, sources close to the singer claim he is seriously considering the role.

He's working with his people to figure out exactly how to respond, a source told E!

Timblerlake is no stranger to the silver screen.

After a handful of flops (including the awful romantic comedy On the Line with fellow NSYNC members Lance Bass and Joey Fatone), Timberlake's first big break arrived in 2006, when he starred as Frankie Ballenbacher in the crime drama Alpha Dog.

The former boy band front man received critical appraise for his drug dealer role, and landed more major films in the years that followed, including Black Snake Moan with Christina Ricci, two Shrek films (providing the voice of Artie) and the Mike Myers comedy, The Love Guru.

In 2010, Timberlake was hired for perhaps the biggest role of his acting career so far: playing Napster co-founder Sean Parker in David Fincher's The Social Network.

As Timberlake fans wait for the former Mickey Mouse Club star to make a decision on the Elton John biopic, here are JT's five best on-screen roles (in no particular order).

Alpha Dog (2006)

Drug dealers. Bruce Willis. Sharon Stone. In Nick Cassevates' Alpha Dog, Timberlake successfully shed his boy band pretty boy image when he took on the role of Frankie. The film, which was released during Timberlake's SexyBack days, earned the singer mostly positive reviews and put him on the radar of major directors and producers.

Justin Timberlake has what it takes to be a genuine movie star, Richard Roeper said at the time.

The Social Network (2010)

If he didn't charm enough with his looks and golden locks, Timberlake's first scene as Sean Parker in The Social Network completed the job. Waking up from a night of partying, Timberlake as Parker delivers line after line, including I founded an internet company that let folks download and share music for free . . . I founded Napster.

Friends with Benefits (2011)

Last summer's other film about friends with benefits was actually called Friends with Benefits. But the takeaway was Timberlake's comedic performance, mixed with random moments of Third Eye Blind and rap, as Mila Kunis played his friend with said benefits.

Bad Teacher (2011)

Timberlake's other film of 2011 starred his ex-girlfriend, Cameron Diaz, as a drunk, gold digging middle school teacher. Her attention quickly turns to the new substitute teacher, Scott Delacorte (Timberlake), a wealthy, nerdy, all-round spiffy guy -- on the surface, anyway. (Recall hilarious hotel room scene between Timberlake and Diaz; and it's not what you think).

Saturday Night Live (2003, 2006, 2009, 2011)

OK, so these episodes were not in movie theaters, but Lorne Michaels and the SNL crew were so impressed with Timberlake's acting skills that they hired him three more times after his 2003 debut.

To refresh your memory, Timberlake's most notable sketches have included: D--k in a Box, The Barry Gibb Talk Show (with Jimmy Fallon), Mother Lover, Breakfast Competition (Omletteville), Single Ladies video with Beyonce and Classic Peg (Target with Kristen Wiig).
