The Gothic-inspired interior makes a strong contrast with the modern exterior.
Together with the Tooting Granada interior, it belongs to the most elaborate purpose-built cinemas in the UK.
It has been described as "reproducing the style and ambiance of a cathedral, a combination and distillation of Venetian Renaissance and Spanish Gothic, with distinct echoes of the Doge's Palace and the cathedral of Burgos".
At the time, the Architect & Building News wrote that it had "a complexity and lavish exuberance rare even in cinema decoration".
The opening brochure called it "the most romantic theatre ever built".
The seating capacity in 1937 was 2434.
After closing as a cinema, the building was used as a bingo hall and a church, but the interior has been largely preserved.
The main stalls and balcony seating, which was removed in the 1960s, was replaced in 2013.

Five sets of entrance doors lead into the vestibule, decorated with pilasters.
Three sets of doors with wrought-iron bars and cast-iron handles lead into the double-height foyer with galleries on three sides.
The foyer has a coffered ceiling, a large central chandelier, four smaller ones and six pairs of wall lights, all in Gothic style.
On the far side, a grand staircase leads to the galleries and the balcony seating area.
The back wall is entirely panelled with gilded frames with rounded and pointed arches.
The four outer bays are decorated with figures painted in Italian Renaissance style, probably by Vladmir Polunin (1880–1957).

The auditorium is also in a style partly based on Medieval and Renaissance architecture.
It has elaborate coffered ceilings in red and green and five large chandeliers.
The imposing ante-proscenium is divided into three sections, separated by pilasters.
The central feature is a monumental Romanesque style arch with jambs made up of seven columns and a tympanum extending up into a pointed gable.
The upper stages of the ante-proscenium are made up of Gothic gables and rows of niches and trefoils.
Some panels are painted with representations of lions and unicorns (possibly also by Polunin).

The balcony foyer ("Hall of Mirrors") features trefoil-arched mirrors and mirror-faced pilasters on both sides of the elongated space.
It has a pitched ceiling with fabric-like decorations in white, red and gold, and a row of French "teardrop" chandeliers.
The balcony is reached through entrances with Gothic panelling, and on the other side, by two vomitories.
