Musical enthusiasts are in for a treat as one of the most cherished film adaptations of a legendary stage musical is now available to watch at no additional cost.

Widely regarded as one of the greatest musical films ever produced, it's the perfect pick-me-up to welcome the eagerly anticipated spring sunshine.

The hit 2008 movie not only wowed audiences but also spawned a highly praised sequel in 2018, which viewers can also stream for free on the same service.

This catchy, foot-tapping spectacle centres on a bride-to-be who learns she might be the offspring of any one of three men her mother had romantic escapades with during a sultry summer in the '70s.

Indeed, we're referring to Mamma Mia!, reports the Express, which, along with its follow-up, Mamma Mia! Here We Go Again, has recently been added to ITVX.

Featuring classic tunes from ABBA, the film boasts an all-star ensemble including Amanda Seyfried and Meryl Streep, with Christine Baranski, Pierce Brosnan, Dominic Cooper, Colin Firth, Stellan Skarsgård, and Julie Walters also gracing the cast.

Devotees assert that Mamma Mia! stands out as one of the finest musical movies of the 21st Century, perhaps even of all time.

One ecstatic five-star review on Google reads: "With this music, watching Mamma Mia is like watching a musical epic unfold in front of your very eyes!

"Mamma Mia was created to lift you up and will have you singing along to every single lyric! No matter if you are male, female, old or young, it is an experience that must be shown to everyone.

"It is perfect for one of those terrible days when you need something to boost your mood."

Another enthusiastic fan exclaimed: "Hands down the best musical I've ever seen. I've watched a lot of musicals, but this one is my favorite.

"The cast is fantastic, with many well-known actors who all bring something special to the film. The songs are amazing-ABBA has so many great tracks, it's hard to choose my favorites."

"I have watched this since I was little and I will watch it until I die."

One glowing review on Letterboxd captured the sentiment: "Talented. Brilliant. Incredible. Amazing. Show stopping. Spectacular.
