Plus David Bowie's Labyrinth is heading back to the Top 40.

Straight Outta Compton could be heading straight for Number 1, according to this week's Official Video Chart Update.

Universal Pictures' biographical drama about the rise and fall of hip-hop group N.W.A is currently leading the way as this week's best selling DVD/Blu-ray, with sales of almost 33,000 at the mid-week stage. 

The movie's soundtrack - released last Friday (January 8) - is also heading for the Top 40 on this week's Official Compilations Chart, currently at Number 39. The album features songs mainly by N.W.A, but also Ice Cube, Eazy-E, Dr. Dre and Snoop Dogg.

Meanwhile, US action thriller No Escape, which stars Owen Wilson, LakeBell, and Pierce Brosnan, is new at Number 2 (13,000 sales), and BBC's Sherlock - The Abominable Bride debuts at 3 with sales of just over 10,000 at the halfway stage. 

Completing this week's Top 5 are Lorraine - Living To The Max at 4, and last week's chart-topper Davina - 5 Week Fit is at 5.
