1998 Winter Eien Densetsu [Kaiteiban] - The Final First Stage!! (Senshuuraku)

3:14 Orleans no Sei Senshi

Several French words appear here:

lilas = lilac
Les etoiles = The Stars
La lumiere = The Light
La Fatalite = The Fatality
La Fatalite de l'amour = The Fatality of Love

6:16 Banzai

A play on this musical's sponser, Bandai, the toy company (omocha) whereas
Banzai makes rice cakes (omochi). The sponsor's character is also a reference to the
Tamagotchi character Oyajitchi. Tamagotchi is also made by toy company Bandai.

07:33 Mr. Banzai

The image on the Director's back is of the Banzai gesture.

17:33 Mr. Kyoto

A reference to the city of Kyoto, this character's voice greatly resembles
the dialect there. 

19:09 One Role

All of Ryuuji Kasahara's roles have been villains... 
Kunzite, Death Ra, Tiger's Eye, MC Fly, The Director,
The Physical Education Teacher, Banzai, Kyoto and Kyaos. By this point
Banzai and Kyoto are too similar and it seems as if he's not trying anymore.

Yuuta Mochizuki has played Mamoru Chiba for several years at this point.

25:47 Completely unfounded

Setsuna literally said "It's without roots or leaves" meaning there is 
no basis of evidence.

27:17 Private Police Box

That's a box belonging to private police not a police box that is private.

27:48 Octopus

That octopus is from the Sailor Stars Kaiteiban musical.

28:49 Yume no Naka e

They're singing along to a famous song by Yousui Inoue named "Yume no Naka e"
(Into the Dream) which resurged in popularity in the 90s as the ending song 
for the anime "Kareshi Kanojo no Jijou" (His and Her Circumstances) known
as Kare Kano in English performed by Aysuko Enomoto and Chihiro Suzuki. 

30:05 Planets

The names of the planets end in "sei" in Japanese, such as "Suisei" (Mercury)
but Yaten said "anta no sei" (your fault) at the last turn and then "dare no
sei" (whose fault).

30:30 Hot Boxed Lunches

Types of bentou boxes end with -ben such as Noriben (Seaweed boxed lunch)
at the last turn, Taiki said however, "kanben" (forgive me). This is because
Hikari Ono has extended the scene from the original script.

31:41 It's You / My Darling

This is a reference to the 1974 hit song "Anata" (which means "You" but is
also a term of endearment from a wife to her husband) which was composed
and performed by none other than the Sailor Moon Musical composer Akiko Kosaka.

38:59 Galaxy's finest

A few lines from the cut song "Tenkuu no Utage" (Summer 1997)

42:41 Use her, that is to say use her

A few more lines from the cut song "Tenkuu no Utage" (Summer 1997)

48:51 East, South, West, North

Ryuuji Kasahara had a song in the original Eien Densestu (Summer 1997) that
these lines are from called "Mizusakiannainin no Game" (The Pilot's Game)

49:24 The Doll

This puppet is Oyajitchi, a character on the Original (Japanese) Tamagotchi
made by Bandai. He is a popular character, particularly in the 90s.

1:18:56 Ninja

Rather than mimicking Usagi's "nanimono" as Chibichibi usually would she
said "shinobinomono" (ninja).
