Another super week at the top of the UK DVD chart is in the stars for Guardians of the Galaxy Vol. 2

Plus the Big Bang Theory's landmark tenth season is selling well this week.

The two bestselling DVDs and Blu-rays this week are making for an intergalactic battle at the top of the Official Video Chart, the UK's tally of physical home entertainment sales.

In today's midweek Chart Update, which gives an indication of what Sunday's final Official Video Chart will look like, it appears last week's Number 1 Guardians of the Galaxy Vol. 2 will secure the top spot for another week.

Based on sales from Monday through Wednesday, Guardians, which stars the likes of Chris Pratt, Karen Gillen and Vin Diesel, is outselling its nearest rival by six-copies-to-one. In the runner-up spot currently is Season 10 of The Big Bang Theory, so we have two space-related titles proving popular this week.
